2 ## This file is in charge of setting our paranoid flags with regard to warnings and optimization.
4 ## These flags do break some classical CMake tests, so you don't
5 ## want to do so before the very end of the configuration.
7 ## Other compiler flags (C/C++ standard version) are tested and set
8 ## by the beginning of the configuration, directly in ~/CMakeList.txt
