[CMake] fortran compiler failed to compile simple test program

[Ette, Anthony (CDS)]

Any ideas?  Our FORTRAN compiler (Concurrent Computer Corporation port of f77) is failing to compile simple test program because the linker can't find -lrt (highlighted below).  Have you ever seen anything like this?  How can I remedy?

  It fails with the following output:
