This says that CMake's FortranCInterface module successfully detected
the mangling and verified that Fortran and C++ can be used together
with these compilers.  This is good.

This message comes from Trilinos's other Fortran mangling detection
that predates the CMake FortranCInterface module.  There are probably
messages from it in the configure output.  Please post a more complete
log.

You can also try running cmake with the "--trace" option to see
a verbose log of how CMake is processing the input files.  Look
for FortranMangle.cmake lines running, and for code setting
FC_FUNC_DEFAULT.
