Run Command after generation step in CMake

I have a command line tool that should be run after CMake created my .sln-file. Is there any way to do that using CMake?

Using execute_process(COMMAND ..) at the end of the CMakeLists.txt does 开发者_JS百科not help because this is executed after the Configure step, however, the .sln-file is created in the generation step.

Thanks a lot!

A rather horrifying way to do it is by calling cmake from cmake and doing the post-generate stuff on the way out of the parent script.

option(RECURSIVE_GENERATE "Recursive call to cmake" OFF)

if(NOT RECURSIVE_GENERATE)
    message(STATUS "Recursive generate started")
    execute_process(COMMAND ${CMAKE_COMMAND}
        -G "${CMAKE_GENERATOR}"
        -T "${CMAKE_GENERATOR_TOOLSET}"
        -A "${CMAKE_GENERATOR_PLATFORM}" 
        -DRECURSIVE_GENERATE:BOOL=ON 
        ${CMAKE_SOURCE_DIR})
    message(STATUS "Recursive generate done")

    # your post-generate steps here

    # exit without doing anything else, since it already happened
    return()
endif()

# The rest of the script is only processed by the executed cmake, as it 
# sees RECURSIVE_GENERATE true

# all your normal configuration, targets, etc go here

This method doesn't work well if you need to invoke cmake with various combinations of command line options like "-DTHIS -DTHAT", but is probably acceptable for many projects. It works fine with the persistently cached variables, including all the cmake compiler detection when they're initially generated.

From the following links, it seems like there is no such command to specify execution after CMake generated .sln files.

An alternative is to write a wrapper script as described in one of the above links.

cmake ..
DoWhatYouWant.exe

Yes, add_custom_command paired with add_custom_target got this covered

For an example take a look at my answer to another question

• cmake add_custom_command
