Languages can also be specified in the project command:

  project(Q2P1 C CXX Fortran)

FYI, you can use

  CC=mpicc CXX=mpic++ FC=mpif90 cmake ...

and you do not need to set CMAKE_Fortran_COMPILER at all in the cmake code.

Set the LINKER_LANGUAGE target property:

  http://www.cmake.org/cmake/help/cmake-2-8-docs.html#prop_tgt:LINKER_LANGUAGE

with code like

  set_property(TARGET Q2P1 PROPERTY LINKER_LANGUAGE Fortran)
