Use CMake to find IOS provisioning profiles

If you use xcodebuild to export your archive - you have to specify the provisioning profile to use. And if you have multiple of those (e.g. on a build server), you might run into trouble selecting the proper one from within CMake. This small and easy code snippet might help you to make this a little bit easier.

macro(cp_ios_get_provisioning_profiles PROFILE_NAME PROVISIONG_PROFILES_DIR RESULT)
    file(GLOB FILES ${PROVISIONG_PROFILES_DIR}/*.mobileprovision)
    set(LIST "")
    foreach(FILE ${FILES})
        file(STRINGS "${FILE}" NAME REGEX "${PROFILE_NAME}")
        if (NAME)
            list(APPEND LIST ${FILE})
        endif()
    endforeach()
    if (LIST)
        list(APPEND ${RESULT} ${LIST})
    endif()
endmacro()

You can use this macro e.g. like this:

set(IOS_PROVISIONG_PROFILES_DIR "$ENV{HOME}/Library/MobileDevice/Provisioning Profiles/")
set(RESULTS "")
cp_ios_get_provisioning_profiles("The name in your profile"  "${IOS_PROVISIONG_PROFILES_DIR}" RESULTS)
if (NOT RESULTS)
    message("Could not find matching provisioning profile in ${IOS_PROVISIONG_PROFILES_DIR}")
else()
    message(STATUS "Found provisioning profile hash ${RESULTS}")
endif()
