In my CMakeLists. Why we are doing glog::glog rather than just glog 4. txt to my project, but it is very similar (I had to change te library names, the path). I had to put that work on hold but am planning on returning to it once CMake 3. This works faster as referencing the Deprecated CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY disables the User Package Registry in all the find_package() calls when set to TRUE. 3w次，点赞252次，收藏620次。本文是“轻松搞定CMake”系列博客中的一篇，该篇文章的主要目的是详细讲解一下CMake中搜包命令find_package的使用和原理。find_packakge命令基本介绍在我们实际开发过程中，经常不可避免会使用到第三方开源库，这些开源库可能是通过apt-get install命令自动安装 I'm trying to use find_package to include libraries in CMake. Improve this question. cmake, if I do find_package instead of find_dependency, what would be the effect on my application? In what scenarios it will break? cmake; Share. The sort direction can be controlled using the CMAKE_FIND_PACKAGE_SORT_DIRECTION variable (by default decrescent, e. cmake file and searches after the library on the system and defines some variables like SomeLib_FOUND etc. The locations where CMake searches for the config and version files is considerably more complicated than for Module mode (see Config Mode Search Procedure). minor. When the basic signature is used, the command searches in Module mode first. How to create dependencies in CMake. This is true for CMake 3. See the documentation of find_package() for details on such files. Find_package in a nutshell. Is it possible to undo the find_package and call find_package(. This is important when authoring a library that might be included in a package manager, like vcpkg or a Linux distro's standard repositories. CMake does not include path to link libraries when compiling. 11 is not defined is the root of the problem. cmake is found, it won't try to find libraries outside the path. cmake or PackageConfig. If set to ONLY, then only the roots in CMAKE_FIND_ROOT_PATH will be searched. Found CUDA: /usr/local/cuda (found version "6. I tend to group these parameter in a file I call dependecies. Specifically, I want a project, say called foo, to be accessible like this: I try to create multiple cMake targets using different versions of Python. 23 is released. A user may set the CMAKE_FIND_PACKAGE_PREFER_CONFIG variable to true to reverse CMake and Config/Modules find_package. Here is a workaround but not good enough: CMake find_package dependency on subproject - Stack Overflow. Is it special for Qt or does find_package generate imported targets for all libraries? The A "find module" is a Find<PackageName>. Previous topic CMAKE_FIND_PACKAGE_SORT_DIRECTION I would not recommend CONAN_PKG:: because it will be deprecated for Conan 2. Write better code with AI Security. Search Modes ¶. CMake and FIND_PACKAGE. Sending CMAKE_PREFIX_PATH or <package-name>_ROOT through the command line is also okay. Thus configuring your project using CMake, it should be able to find_package(GTest) using the usual search procedure. I can clone and put them into my project as a git submodule and use add_subdirectory to use them in my project. See command documentation for details. Learn how to use the find_package command to locate and use external packages in CMake projects. In this mode, CMake searches for a file called Find<PackageName>. 04, I am compiling a C++ program, which depends on the following packages: CUDA and OpenNI. If no package configuration file is found then the wording of the failure message must account for both Finds Matlab or Matlab Compiler Runtime (MCR) and provides Matlab tools, libraries and compilers to CMake. The find-files do roughly the following: Look for files belonging to the package in likely locations The CMake manual of Qt 5 uses find_package and says:. ; TBB_<library>_LIBRARY - The path of the That is documented behaviour of find_dependency(). 2. At least one of the C, CXX, or Fortran languages must be enabled. Enabling this variable is equivalent to using cmake--debug-find with the added ability to enable debugging for a subset of find calls. find_program to find an executable. In my cMakeLists I define the Python_ROOT variable and use find_package(Python REQUIRED COMPONENTS Interpreter Development) to get the python library path, version and linking options. This effectively "re-roots" the entire search under given I'm working on project that use some third-party libraries. cmake with our own without disturbing anything else? At this time, it is equivalent to find_package of Xmake/CMake, but it is simpler and easier to use, and it is exactly the same as the use of remote packages. If I have a FindXXXX. This allows someone to replace your dependencies with system-provided ones instead. It is responsible for finding the package, checking the version, and producing any needed messages. Over time, this approach has suffered from several issues across the different supported platforms. The best solution is to get libsoundio to install a config file, but then you'd have to wait on them for it to work. For instance in order to select the highest version one can set: SET(CMAKE_FIND_PACKAGE_SORT_ORDER NATURAL) The things are different for XXXConfig. Hot Network Questions Galton Board optimization "He had to do it. Version support is currently provided Setting to TRUE promotes all IMPORTED targets discovered by find_package() to a GLOBAL scope. We will use Visual Studio to create a basic library The --prefix argument to cmake --install is generally the best way to set an installation prefix because it lets you decouple install-time requirements from your configuration logic. The directory that the CMAKE_FIND_PACKAGE_REDIRECTS_DIR variable points to is cleared at the start of every When not redirected to a package provided by FetchContent, the command arguments determine whether Module or Config mode is used. find_path to find the directory containing a file. The primary task of a find module is to determine whether a package is available, set the <PackageName>_FOUND variable to reflect this and provide any variables, macros and imported targets required to use the package. Then try to locate the GTestConfig. Load 7 more related questions Show fewer related questions Sorted by: Reset to default Know someone who can answer? Share a I've installed all the dependencies and I'am using cmake to build the project, although it stops with the following error: find_package (Threads) changed the order of -lpthread in the cmakelists line above, which gives the same error; used different versions o gcc/g++: tried 4. I think you are mixing different concepts. Paths with lib/<arch> are enabled if the CMAKE_LIBRARY_ARCHITECTURE variable is set. patch> is the version number of the project to be installed. Boost CMake¶ If Boost was built using the boost-cmake project or from Boost 1. cmake files that provide information about where to find the headers and libraries of the other modules. cmake scripts that attempt to locate such libraries. cmake scripts, which are processed in CONFIG mode of find_package. If the package is optional, I've got the same problem as you. The cmake_find_package generator creates a file for each requirement specified in a conanfile. A user may set the CMAKE_FIND_PACKAGE_PREFER_CONFIG variable to true to reverse 1. cmake and a <lowercaseName>-config-version. By default, if the system library is not found, it will prompt failure. The command has two very distinct ways of conducting the search: Module mode. Here's and example usage: find_package(FluidSynth REQUIRED) The CMake manual of Qt 5 uses find_package and says:. It already knows where to find those libraries. Controls the default behavior of the find_package() command for whether or not to search paths provided by the User Package Registry. This question talks about how to tell CMake to link to the GMP library (external). I have an External project called messages. This module looks for this file and, if found, returns its results with no further action. 1. CMake has property BUILDSYSTEM_TARGETS but it lists only non-IMPORTED targets, so it doesn't fit. In Config mode, it will look for a find_package to find and load settings from an external project. In the docs, FindXXX. By the way, Python3 version 3. cmake file to <filename>. The workhorse of dependency discovery This tutorial shows how to export a CMake library to a package and import it from a different project using the find_package() command. cmake Add the installation prefix of "myLib" to CMAKE_PREFIX_PATH or set "myLib_DIR" to a directory containing one of the above files. This succeeds, great! However, it turns out to be the wrong version of the package. cmake file is searched). cmake). cmake file for use with the find_package() command's config mode. CMAKE_FIND_PACKAGE_NO_SYSTEM_PACKAGE_REGISTRY disables the System After performing a find_package, perhaps you can't make cmake print exactly the variables that the package specifically defined, but perhaps you may appreciate the following code from this SO answer, which gives lists all of the variables defined at a certain point in your cmake files. The config and version files are typically installed as part of the package, so they tend to be more reliable than Find modules. 24. The third argument lists details about the find result so that if they change the message will be displayed again. 6 and 4. Updating CPM. 0 or a compatible (as you defined “compatible”) library version. Where should find_package() for these common libraries be called? So, I want to create a C library that can be installed in such a way that it is easily usable in other projects with the find_package function in cmake. cmake) If find_package() is called without an explicit mode option (MODULE, CONFIG, or NO_MODULE) and no Find<pkg>. This script makes use of the standard find_package() arguments of <VERSION>, REQUIRED and QUIET. Whether a package has been found is determined using the <NAME>_FOUND variables. patch[. I am not sure, if there is way 2. The Google Test gtest library, if found; adds Thread::Thread automatically. If the file is found, it is read and processed by CMake. It is intended to be set by the project. For find_package CMake offers a special mechanism on Windows called the package registry. Common CMake pattern to obtain the list of created "objects" is to intercept commands created such object and force them to add objects into the list. cmake trying to find libraries outside your SDK path. cmake If it doesn't exist i'd like to initiate a checkout and add the find_package on the other hand is CMake's very own mechanism for solving the same problem. cmake file in the installation directory. So for the zlib/1. 0. This makes functions or utilities exported by the package available for consumers just by setting find_package(<PKG-NAME>) in the CMakeLists. Your concern is primarily with XX-config. This works faster as referencing the library project’s directory using the add_subdirectory() command, as the exporting mechanism allows precisely selecting which targets to export. look for the SDL2 component and 3. It furthermore imports the Qt6::Core target that we use below. txt Learn how to write and use find_package files for CMake projects with examples and explanations. The macro also obeys the QUIET argument to the find_package command. cmake mylib-config. The CMake command find_package has two modes (Config mode and Module mode) to find and load the CMake configuration of an external project. See the different search modes, signatures, options and variables for finding and configuring packages. TBB_ROOT_DIR - The base directory the of TBB installation.

Follow asked May 9, 2018 at 23:07. 0 REQUIRED) will look for the 1. Then, you have FindXX. If no [version] and/or component list is given to a recursive invocation inside a find-module, the corresponding arguments are forwarded automatically from the outer call (including the EXACT flag for [version]). txt doesn’t always succeed, cases: As a Visual Studio 2019 cmake proejct it works As a Qt Creator project it fails When configure and generate with cmake-gui it fails If find_package() is called without an explicit mode option (MODULE, CONFIG, or NO_MODULE) and no Find<pkg>. Specify the modules that you want to be included in attribute GTest::GTest. 22. Did CMake’s find_package cares less about how variables are named, but does care about how the _FOUND variables are named. Package roots are maintained as a stack so nested calls to all find_* commands inside find modules and config packages also search the roots as prefixes. If the dependency might be cross-compiled relative to your To control the order in which find_package checks for compatibiliy use the two variables CMAKE_FIND_PACKAGE_SORT_ORDER and CMAKE_FIND_PACKAGE_SORT_DIRECTION. cmake at /usr/local/lib/cmake. So now you can add this path to the CMAKE_PREFIX_PATH variable. Sign in Product GitHub Copilot. Somewhere I read that it's possible to query git to checkout repositories from within cmake scripts.

I am using ExternalProject_Add in order to fetch and build the project. cmake in the CMAKE_MODULE_PATH followed by the CMake installation. Then in the CMakelists. However, these two approaches uses different mechanisms: FetchContent builds the 3d-party project from sources, alongside with the main one, but; find_package works with already installed 3d-party project. cmake, “find package” or “find modules” uses . 11 didn’t change anything. After watching excellent talks by both Craig Scott and Deniz Bahadir I reached out to them directly via e-mail and got some very helpful responses. <filename> is the output filename, which should be in the build tree. Previous topic CMake has a rich ecosystem of modules for finding software dependencies. This applies all the way back to CMake 2. <major. This variable is ignored when CMAKE_FIND_USE_PACKAGE_REGISTRY has been set. If no VERSION is given, the PROJECT_VERSION variable is used. It effectively means a config package must be found for the dependency, and the This file uses <PKG-NAME>_BUILD_MODULES values to include the files using the include() CMake directive after the targets are created. This can be skipped if NO_CMAKE_PACKAGE_REGISTRY is passed or by setting the CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY to TRUE. 2. 11 package, a Now a find_package() call of the form find_package(my_library 1. If set to NEVER, then the roots in CMAKE_FIND_ROOT_PATH will be ignored and only the host system root CMake "find_package" command on a package that was not installed is unexpectedly successful. For this to work you either need a CMake find script for the requested library (CMake already ships with a couple of those , but you can easily write your own) or alternatively a package config script provided by the requested library itself. I think the fact that CMAKE_INSTALL_PREFIX affects configure-time logic just reinforces that position. If neither CMAKE_FIND_USE_PACKAGE_REGISTRY nor CMAKE_FIND_PACKAGE_NO_PACKAGE_REGISTRY is set, then find_package() will use the User Package Registry unless the NO_CMAKE_PACKAGE_REGISTRY option is provided. Version support is currently provided When not redirected to a package provided by FetchContent, the command arguments determine whether Module or Config mode is used. Hi @xoorath. lib* includes one or more of the values lib64, lib32, libx32 or lib (searched in that order).

This module finds an installed Fortran library that implements the BLAS linear-algebra interface. txt. My project is a cross-compiled project that develops debugging on x86 machines and deploys and runs on aarch64 machines, depending on the x86 and aarch64 versions of the same package, but cmake doesn't seem to re-search for packages when switching architectures. That's why it does not work when you put it into . I want to use a custom location where all libraries are installed. Example: When not redirected to a package provided by FetchContent, the command arguments determine whether Module or Config mode is used. If the EXACT option is given only a version of the package claiming an exact match of the requested version may be found. Excluding cmake's own distribution modules with `find_package()` 0. cmake Add the installation prefix of "Mylib1" to CMAKE_PREFIX_PATH or set "Mylib1_DIR" to a directory containing one of the above files.

Look for CMake module FindPostgreSQL. The only thing that the cmake generators will do in this case is set-up some build configuration, like the RPATH or MD /MT Could not find a package configuration file provided by "myLib" with any of the following names: myLibConfig. CMake include_directories does not help to find header files. 0 on it provides a package configuration file for use with find_package's config mode. minor[. In big projects, I find that the time taken for dependency/package-related things often dominates the overall configure time. I think there is no universal way: App CMakeLists. To add a Nuget package reference to a CMake target, we can use the syntax <package-name>_<package-version>. cmake methods. Can CMake tell me which Module or Config file is used for find_package()? 4. find_dependency forwards the correct parameters for QUIET and REQUIRED which were passed to the original find_package() call. can I find the installation location of package X files on my machine after calling find_package(X)? Thanks! If the dependency is third-party, then you should use find_package. CMake Package Support - Includes and Libraries not found. Usually you (or at least consumers of your project!) really want to directly Thanks for your input, that is one way of doing it. So what is Version Selection ¶. This generator is especially useful if you are using CMake using the find_package feature to locate the dependencies. Semicolon-separated list of directories, represented using forward slashes, specifying a search path for CMake modules to be loaded by the include() or find_package() commands before checking the default modules that come with CMake. Input Variables¶ In CMake 3. 31. It covers integrating find_package() and FetchContent. But it take much time to compile these libs, and I can not manage cmake variables in my projects, and install() command make my package contains many things that I don't need. txt file I have This tells CMake to look up Qt 6, and import the Core module. lib-B will be tested before lib-A). g. cmake module it work is done and I simply have to call the find_package statement. 0, you still can use cmake_find_package generator, or even new Conan Toolchain generators which should be the default for Conan 2. Then type sudo make install again How can I setup everything so I can write find_package(MyPack)in the other subprojects?
