CMake 2.8 added a new External Project module, which lets you create a custom target to drive the build of another CMake project. The documentation on this is kind of weak, but it looks like it might do what you want. I think the idea would be to call ExternalProject_Add from your parent project, pointing … Read more
CMake 3.21 introduced the directory property IMPORTED_TARGETS that can be used to get a list of all imported targets. This can be used to derive a list of targets that were imported by a single find_package() call when it is queried before and after the call to find_package(). The code could look something like this: … Read more
If you really need to use file(GLOB …), this CMakeLists.txt should work : cmake_minimum_required(VERSION 3.3) project(bmi) add_definitions(“-Wall” “-g”) include_directories(${PROJECT_SOURCE_DIR}) file(GLOB SRC_FILES ${PROJECT_SOURCE_DIR}/*.cpp) add_executable(bmi ${SRC_FILES}) In this case you have to launch cmake from your build directory every time you add or delete a source file : cmake <your_source_dir> -G <your_build_generator> As Phil reminds, CMake documentation … Read more
I think your best bet is indeed to delete the cache and re-create it. In fact, I tend to go further and remove the entire build tree if I need to move the source, but this is probably overkill. The CMakeCache.txt file can be edited via the CMake GUI or by hand if you’re sure … Read more
You can use the command cmake –build . –target install –config Debug for installation. CMake’s build tool mode supports further arguments that are of interest in this case. You can select the target to build by –target option, the configuration to build by –config option, and pass arguments to the underlying build tool by means … Read more
You can call cmake –build like this: cmake –build . –target MyExe –config Debug This would be run from your build root, since the directory is passed as ., and would build the target MyExe in Debug mode. If your build tool is a multi-configuration one (like devenv on Windows), the –config argument matters. If … Read more
Quick solution: apt-get install zlib1g-dev
While it is not directly written in documentation pages for versions prior to v3.14, CMake functions described under cmake-modules section requires including specific module. As function ExternalProject_Add is described in the documentation page titled as “ExternalProject”, you need to use include(ExternalProject) before using it. Same strategy works for any other modules except Find<name> ones. Those … Read more
I am using the following two lines in the CMakefile set(CMAKE_MACOSX_RPATH 1) set(CMAKE_INSTALL_RPATH “${CMAKE_INSTALL_PREFIX}/lib”) (the first one is required only if you use MacOSX)
Is there a command with which I can clean up all those generated project files? Yes – if you do an out-of-source build (as recommended). To do so, create a directory – for example, build – within your projects directory and run CMake from there: mkdir build cd build cmake .. make (Or tell your … Read more
