9/25/2023 0 Comments Cmake include cmakelists.txt oncwSo CMake first searches for a file named dependencies.cmake relative to the CMAKECURRENTLISTDIR (I think it might be CMAKECURRENTSOURCEDIR ). Executables and windows dll files go into bin directory, libraries go into lib directory, and public headers go into include directory at the destination. From the docs for include: If a module is specified instead of a file, the file with name .cmake is searched first in CMAKEMODULEPATH, then in the CMake module directory.Install(TARGETS): to install compiled libraries and their headers in the assigned install directory you set when running cmake -install blah blah. So first compile geo then link it to app executable. The current directory contains a CMakeLists.txt file. Target_link_libraries(): to tell CMake that app is dependent on geo library. For example, the nodejs module shows the version of Node.js that is currently installed on your. Target_include_directories(): is for making source files aware of the location of private headers relative to the project directory. SHARED means a shared library, you can also make a static library with STATIC keyword, or an object file with OBJECT keyword. dll.Īdd_library(): to define a library target, geo. New in version 3.15: For every project () call regardless of the project name, include the file named by CMAKEPROJECTINCLUDE, if set. If (MSVC): checking CMake is employing MS Visual C++.ĬMAKE_WINDOWS_EXPORT_ALL_SYMBOLS: This is necessary for MSVC to create a symbol file. The toolchain file may be re-read when enabling a language for the first time. To build an example, go to its directory in a terminal and runĬmake_minimum_required ( VERSION 3.23 ) project ( geometry LANGUAGES CXX ) if ( MSVC ) set ( CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS ON ) endif () add_library ( geo SHARED ) target_include_directories ( geo PRIVATE "$" ) add_subdirectory ( "shape" ) add_subdirectory ( "square" ) add_executable ( app ) target_sources ( app PRIVATE "example/app.cpp" ) target_link_libraries ( app PRIVATE geo ) install ( TARGETS geo FILE_SET HEADERS ) you have a compiler like GCC, Clang, Intel, or MS Visual C++ installed on your operating system.Įxamples are on GitHub here and their links are mentioned in each section as well.you had a look at my post on CMake programming,.In this post, instead of throwing instructions for some random commands, I aim to explain how to employ modern CMake step by step to build executables (applications) and static/shared/header-only libraries from C++ projects. It has comprehensive but daunting manual instruction. It compiles projects with compilers like GCC, Clang, Intel, MS Visual C++.ĬMake is frequently used in compiling open-source and commercial projects. CMake utilizes build-systems such as Ninja, Linux make, Visual Studio, and Xcode. CMake is a cross-platform software for building projects written in C, C++, Fortran, CUDA and so on.
