Qmake -project searching for fortran sources

[cmazieri]

I have a project that uses some fortran files starting a directory level and going deep some levels.
I know that is possible to create a Makefile for them using qmake and setting some QMAKE variables like:
@
QMAKE_CC = gfortran
QMAKE_LINK = gfortran

CONFIG -= qt
@

But I would like to let qmake find all the fortran files using "qmake -project".

Does anyone know how I can set the the fortran extension ".f95" to "qmake -project" ?
