What are you trying to do ?

1) Compile & Link some Fortran source for a Fortran project ?
2) Compile & Link some mixed language project like C/Fortran or C++/Fortran ?

Usually when using Fortran you should add

enable_language(Fortran)

for mixed language programming you have the
FortranCInterface cmake module:
http://www.cmake.org/cmake/help/cmake-2-8-docs.html#module:FortranCInterface

If you search the ML archive you will find many discussions related to
Fortran Programming.
