CMake script compatibility with Mac OSX #3

Closed jayten closed 5 years ago

jayten commented 5 years ago

The CMake script behaves erratically when used on Mac OSX. It is either not able to find the correct configuration or does not exit the process (execute_process in CMake). The test was performed on OS version 10.13.4 (High Sierra) with following installed using Homebrew

CMake-3.15.0
Gcc-9.1.0
Libmpc-1.1.0
Mpfr-4.0.2
Isl-0.21
Gmp-6.1.2_2
mpich-3.3.1

The following piece of code in the SetFortranFlags.cmake module is creating problem:

# Don't add underscores in symbols for C-compatability
SET_COMPILE_FLAG(CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS}"
                 Fortran "-fno-underscoring")

The issue has been sorted and corrected in the #4.
