How do I get the parent directory path of a path in CMake?
For CMake 3.20 and newer, the recommended way is to use cmake_path with a PARENT_PATH option: cmake_path(GET MYPROJECT_DIR PARENT_PATH PARENT_DIR) For older versions up to CMake 2.8.12, use the get_filename_component command with the DIRECTORY option: get_filename_component(PARENT_DIR ${MYPROJECT_DIR} DIRECTORY) For versions of CMake older than 2.8.12, use the PATH option: set (MYPROJECT_DIR /dir1/dir2/dir3/myproject/) get_filename_component(PARENT_DIR ${MYPROJECT_DIR} PATH)
How can I define a C++ preprocessor macro through the command line with CMake?
A good alternative would be to define a CMake option: OPTION(DEFINE_MACRO “Option description” ON) # Enabled by default Followed by a condition: IF(DEFINE_MACRO) ADD_DEFINITIONS(-DMACRO) ENDIF(DEFINE_MACRO) Then you can turn that option ON/OFF via the command line with CMake using the -D flag. Example: cmake -DDEFINE_MACRO=OFF .. To make sure the compiler is receiving the definition … Read more
Define a preprocessor macro through CMake
For a long time, CMake had the add_definitions command for this purpose. However, recently the command has been superseded by a more fine grained approach (separate commands for compile definitions, include directories, and compiler options). An example using the new add_compile_definitions: add_compile_definitions(OPENCV_VERSION=${OpenCV_VERSION}) add_compile_definitions(WITH_OPENCV2) Or: add_compile_definitions(OPENCV_VERSION=${OpenCV_VERSION} WITH_OPENCV2) The good part about this is that it circumvents … Read more
CMake Error: CMake was unable to find a build program corresponding to “MinGW Makefiles”

If you edit your environment variables via System Properties, be sure to close and reopen the CMake GUI. If you’re more accustomed to using make.exe, install … Read more
CMake configuring fails. “cl.exe is not able to compile a simple test program”
I had the same problem on Win7. What worked for me is what @Andre suggested in the comment: Right-Click->Properties on cl.exe in your VS install directory (the exact path appears in the CMake error); Choose the Compatibility Tab; Check “Run this program as administrator” in the “Privilege Level” box.
How can I decide what to put in my CMakeList.txt’s cmake_minimum_required call?

As an example, failing early, and with a clear message… CMake 3.2 or higher is required. You are running version 2.8.12.2 …is to be preferred over … Read more
