Turned on warning as error in the main CMakeLists.txt file. Removed one warning in util_path by doing a void cast. Overrides compiler flag with Wno-error on a couple of files with errors. Should be fixed later.
Removed unused static function in enkf_main, it gave a warning. Removed warning as error exception in cmake file
Moved the no-warning-as-errors for the cmake check c files into the ert_check.cmake file
Reintroduced enkf_main_invalidate_cache as a commented out function, so that if it is actually used, and someone gets into trouble, it is easier for them to find it.
In stead of using void cast, move declaration into ifdef block
