Summary0003144: cmake fails when fortran modules are saved in an otehr directory that the default one.
DescriptionIn fortran example of cmake (cmake-2.2.3/Tests/Fortran), I added the following line in CMakeLists.txt which tells the compiler to put the modules in directory ./modules:

SET(CMAKE_Fortran_FLAGS "${CMAKE_Fortran_FLAGS} -module ./modules")

after generating the makefile with cmake, i compile and gets this error message:
[...]
Building Fortran object CMakeFiles/test_module.dir/test_module_interface.o
/opt/intel/fc_80/bin/ifort -o CMakeFiles/test_module.dir/test_module_interface.o -module ./modules -c /home/betsubetsu/cmake-2.2.3/Tests/Fortran/test_module_interface.f90
/home/betsubetsu/cmake/bin/cmake -E cmake_copy_f90_mod TEST_MODULE test_module.mod.stamp
Error copying Fortran module "TEST_MODULE". Tried "TEST_MODULE.mod" and "test_module.mod".
make[3]: *** [CMakeFiles/test_module.dir/test_module_interface.o.provides.build] Error 1
make[3]: Leaving directory `/home/betsubetsu/cmake-2.2.3/Tests/Fortran'
make[2]: *** [CMakeFiles/test_module.dir/test_module_interface.o.provides] Error 2

make[1]: *** [CMakeFiles/test_module.dir/all] Error 2
make[1]: Leaving directory `/home/betsubetsu/cmake-2.2.3/Tests/Fortran'
make: *** [all] Error 2


If i don't put the option '-modules' then it works fine.

I should say that the compilation fails, not cmake.

Unfortunately this will be non-trivial to fix and we have no time to spend on Fortran support right now. If you want to try to create a patch we may accept it. Here is how to get started:

There is no (easy) way CMake will be able to recognize -module flags for all compilers and magically know where to look for the exported module files. Instead we should add a target property called Fortran_MODULES_DIR or something like that. The target property can be initialized from a CMAKE_Fortran_MODULES_DIR variable to allow a simple global setting. The CMakeFortranInformation.cmake file should have a variable such as CMAKE_Fortran_MODULES_DIR_FLAGS or something along those lines to tell the generator how to give the modules directory to the compiler. Then the fortran dependency scanning for a target can be updated to know about the modules directory since it is now a target property.

This bug has been fixed by changes described in bug 0005809.

The target property Fortran_MODULE_DIRECTORY may now be set to request that modules be placed in another directory. The property may be set on all targets by setting the variable CMAKE_Fortran_MODULE_DIRECTORY before creating any targets. Dependencies are tracked correctly.
