[CMake] Question about a simple macro.

[Steven Truppe]

OK, i don't realy understand why it does work but i got it working:

include(CMakePrintHelpers)
macro(bsMergeFlags flags_to_add flags)
     set(flags_to_add ${flags_to_add} ${ARGN} )
     cmake_print_variables(flags_to_add)

     message(STATUS "bsMergeFlags ${flags_to_add}")
     list(APPEND flags ${tmp})
     message(STATUS "------------")
endmacro()

Now my problem is that the content of flags_to_add is correct when i use
cmake_print_variables but not when i try to use it in a message() call.


I think i do miss some very important part when it comes to variables -
i'm now studying the hole chapter again, hopefully i understand it then.


I hope you guys can help me.


best regards!
