There's a newly open sourced fortran compiler flang:
https://github.com/flang-compiler/flang
The CMakeTestFortranCompiler.cmake erroneously says that the compiler
doesn't work.
-- The Fortran compiler identification is Flang 99.99.1
-- Check for working Fortran compiler: /usr/local/bin/flang
-- Check for working Fortran compiler: /usr/local/bin/flang -- broken
CMake Error at
/usr/local/share/cmake/Modules/CMakeTestFortranCompiler.cmake:45 (message):
The Fortran compiler
"/usr/local/bin/flang"
is not able to compile a simple test program.
It fails with the following output:

the fortran compiler does work if you remove the -E flag from the the
compilation command.
Is this an issue something that can get some attention?
Best,
Owen
