Hi Marcel,

In fact my CMakeLists.txt file starts with the following lines:

cmake_minimum_required(VERSION 2.6.2)
set(CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR})
project(my_project Fortran)

in that case I have the problem described previously e.g. the 
Compiler/G95-Fortran.cmake file is actually parsed but its contents not 
used.

If I try in the following order:

cmake_minimum_required(VERSION 2.6.2)
project(my_project Fortran)
set(CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR})

the file is even not parsed at all.
