[CMake] Program with Qt opening with a bash screen on windows before showing the gui...

[Michael Jackson]

And in a cross platform environment you want to detect the system being compiled for and insert the proper keyword to "add_executable()".

    # Default GUI type is blank
    set(GUI_TYPE "")
    
    #-- Configure the OS X Bundle Plist
    if (APPLE)
        SET(GUI_TYPE MACOSX_BUNDLE)
    elseif(WIN32)
        set(GUI_TYPE WIN32)
    endif()

add_executable(myprogram ${GUI_TYPE} ${SOURCES})

Just for completeness.

If you search the CMake Wiki there is a complete working Qt example which has some of the deployment issues worked out also.
