Prevent cmake to run cpack

I have a CMake project where I want to prevent make package to do anything more than print a message on some platforms.

I know how to add a message, even a fatal one, but that runs during cmake-generation, not during builds. Do I have to resort to some add_custom_command? And that won't give me what I want, since that creates a new build target...

How can I override the package target for some platforms to just show a message?

Solution

  • As shu pointed out, you can do something like this:

    if (! WIN32)
    include(cpack)
else()
    cmake_policy(SET CMP0037 OLD)
    add_custom_target(package
        #add dependencies on other targets here
        #[[DEPENDS install]]
        COMMAND ${CMAKE_COMMAND} -E echo "custom target for non windows platforms!"
)
endif()

    Note that by default, you will not be allowed to override reserved targets like test and package. We are turning off that policy here to write our own package target.
