We can add include and libraries by adding lines like the following, INCLUDES += -Imyincludes Vs adding include and library path in Make My plain CMakeLists.txt will look like the following, cmake_minimum_required(VERSION 2.8)Īdd_executable(testapp $) While Make is flexible tool for rules and recipe, CMake is a layer of abstraction that also adds the configuration feature. If it is not then adding to the reply of I am trying to make it simple by hiding the details. If this question is about a sample Makefile output of the CMakeList.txt file then please check the cmake-backend sources and generate one such Makefile. Sources and build instructions are available at. Second, you perform the actual build in the selected build system. The build system can be passed to CMake as a parameter however, CMake makes reasonable default choices depending on your system configuration. make on Unixes or VC++ or MinGW + Msys on Windows). This creates a Makefile or something equivalent, depending on the build system of your choice (e.g. $(CC) $(CFLAGS) $(INCDIR) $ in your build directory or by running some GUI client). $(CPP) -shared mydynlib.o -o libmydynlib.so $(CC) main.o $(PROGOBJS) $(LIBDIR) $(LIBS) -o prog Prog: main.o $(PROGOBJS) mystatlib mydynlib Makefile by default builds a release target, but offers also a debug target: #Makefile The library libstuff.a in stuff/lib and its header in stuff/include. prog is linked against libmystatlib.aĪnd libmydynlib.so which are both also built from source. Executables and windows dll files go into bin directory, libraries go into lib directory, and public headers go into include directory at the destination.The following Makefile builds an executable named prog from the sources Install(TARGETS): to install compiled libraries and their headers in the assigned install directory you set when running cmake -install blah blah. So first compile geo then link it to app executable. Target_link_libraries(): to tell CMake that app is dependent on geo library. Target_include_directories(): is for making source files aware of the location of private headers relative to the project directory. SHARED means a shared library, you can also make a static library with STATIC keyword, or an object file with OBJECT keyword. dll.Īdd_library(): to define a library target, geo. If (MSVC): checking CMake is employing MS Visual C++.ĬMAKE_WINDOWS_EXPORT_ALL_SYMBOLS: This is necessary for MSVC to create a symbol file. To build an example, go to its directory in a terminal and runĬmake_minimum_required ( VERSION 3.23 ) project ( geometry LANGUAGES CXX ) if ( MSVC ) set ( CMAKE_WINDOWS_EXPORT_ALL_SYMBOLS ON ) endif () add_library ( geo SHARED ) target_include_directories ( geo PRIVATE "$" ) 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.
