set_source_files_properties() should be able to set COMPILE_FLAGS for single 
files.
* you might also write a file which only does some #define/#undef's and then 
includes the file in question ?
* you might build a static library consisting only of that one file, if 
necessary in an own subdirectory (which has only the CMakeLists.txt  with 
add_library(foo STATIC ../the_file.c), basically)
