include(set_compiler_flag.cmake)

3. Then, we try a list of C flags:

set_compiler_flag(  working_compile_flag C REQUIRED  "-foo"             # this should fail  "-wrong"           # this should fail  "-wrong"           # this should fail  "-Wall"            # this should work with GNU  "-warn all"        # this should work with Intel  "-Minform=inform"  # this should work with PGI  "-nope"            # this should fail  )message(STATUS "working C compile ...
