 # HACK!!! If the version of gcc is 4.8 or greater, we add -ftrack-macro-expansion=0 
 # and -save-temps into compiler to reduce the memory consumption during compilation.
 # See http://bugs.debian.org/726009 for more information
 # Can be removed later, if gcc fixes its regression
 # Taken from http://stackoverflow.com/questions/4058565/check-gcc-minor-in-cmake
