Post build step only for release build

I'm trying to setup a post-build command for CMake, which I have done using the ADD_CUSTOM_COMMAND directive as stated in the CMake documentation. What I'd like to do though, is only have the post-build run if I am creating a release build of my executable.

How does one accomplish this?

Solution

  • For Makefile-based generators you can check the CMAKE_BUILD_TYPE variable and act upon its value:

    if(CMAKE_BUILD_TYPE STREQUAL Debug)
    message(STATUS "Do debug stuff")
elseif(CMAKE_BUILD_TYPE STREQUAL Release)
    message(STATUS "Do release stuff")
elseif(CMAKE_BUILD_TYPE STREQUAL RelWithDebInfo)
    message(STATUS "Do release with debug info stuff")
elseif(CMAKE_BUILD_TYPE STREQUAL MinSizeRel)
    message(STATUS "Do minimal size release stuff")
endif()

    For Visual Studio based builds, this SO question seems to suggest that CMAKE_BUILD_TYPE also works with VS 2005+.
