Is the compiler hosted natively on that platform or are you
cross-compiling to it?

That would be useful, thanks. Version information should also
be made available via preprocessor macros.

Okay. If -lrt is the default for the compiler why might "rt" not
be found?

A toolchain file is normally used for true cross-compiling.
You may be able to use one here too, but if you want to skip
the compiler checks then you need to use the CMakeForceCompiler
module's helpers within the toolchain file. First I think we
should identify why the compiler doesn't work for the simple
test case though. Maybe some other fix is needed.
Does building a simple test program by hand work?
$ cat test.f
PROGRAM TESTFortran
PRINT *, 'Hello'
END
$ cf77 test.f
If the compiler requires some special environment to be loaded
then it is your responsibility to do that before running CMake.
Thanks,
