When you want build time evaluation you may write a CMake script

remove_some_file.cmake which:
   1) does the GLOB for building the LIST_OF_FILE
   2) execute_process cmake -E remove ${LIST_OF_FILE}

then in your CMakeLists.txt you add a custom_command/target which
executes:

cmake -P remove_some_file.cmake.

That way the list of file will be built at "build" time.
