# This function works around an 'issue' with CMake, where

# set_source_files_properties() only works in the scope of the file. We want
|

# to set properties for the source file on a more global level. To solve this,
|
|
# this function records the flags you want, and a macro adds them in the root
|
|
# CMakeLists.txt.
