To add_executable indicates that it is a Windows application That your executable is a console application. Your libraries and executables using add_library andĪdd_executable. For large projects that have multiple directories, create aĬMakeLists file in each directory as described in the section on sourceĭirectory structures at the beginning of this chapter. Next, add all of your source files intoĬMake variables. ![]() As always, this file should start withĬmake_minimum_required and project command thatĭefines the name of the CMake project. Will need to create a CMakeLists file at the top of your source codeĭirectory. To convert a Visual Studio solution to CMake involves a few steps. #cmakedefine into a #define if it is not defined, it willīecome a commented out #undef. The variable is defined then configure_file will convert the Variables using the C pre processor by using #cmakedefine VAR. set( CMAKE_RUNTIME_OUTPUT_DIRECTORY $ as a Source files to compile in their subdirectories. Have a single Makefile at the top-level directory that lists all the One option that many Makefile-based projects use is to By having a CMakeLists fileĪt the top of the project, you can use the add_subdirectoryĬommand to step down into the documentation directory where itsĬMakeLists file can install the documentation (you can have aĬMakeLists file for a documentation directory with no targets orįor projects that have source code in multiple directories, there areĪ few options. Support files from the other directories. Second, you may want to install documentation or other ![]() Must run CMake on the subdirectory of the project, instead of the mainĭirectory. First, it can be confusing to some people that they Even ifĪll of the source code is in a subdirectory, we highly recommendĬreating a CMakeLists file for the top level directory. ![]() Level directory or in a directory named src or source. vtk though.Most small projects will have their source code in either the top Where does this path come from? At this point i am more interested in why the old project does work, than why the new one doesn't.Įdit: I am trying to use pcl. ![]() In the old project the first occasion where i encountered the correct path ( /usr/lib64/vtk) was in the linker script. It got really strange when i grepped through the VTKConfig.cmake scripts and realized that VTK_LIBRARY_DIRS is never actually set. So i thought that maybe the VTKConfig.cmake actually calls link_directories so i examined the LINK_DIRECTORIES property of my dir. When i examined PCL_LIBRARY_DIRS i noticed, that it just contains /usr/lib64. However when i eliminate side-effects by calling find_package from another subdir and only use the given variables the vtk libraries that pcl needs are not found at all. The linker script correctly contains references to /usr/lib64/vtk/vtkSomeLibrary.so.1. In an old project there is the following section find_package (PCL 1.7 REQUIRED COMPONENTS common io) The one i am having a problem with is the one containing the library dirs for link_directories. Each module yields an object-library and a bunch of variables that contain metainformation necessary to put the modules together. I am using a project structure for cmake that is a little unusual. ![]()
