Capture module file dependencies in CMake

Browse Source 
The modulefile la_xisnan.F90 depends on the modulefile
la_constants.f90 but this dependency is not expressed in the CMake
rules. In some parallel builds we have observed failures where
compilation of objects that depend on la_constants.mod starts before
compilation of la_constants.f90 has finished.

This patch modifies CMakeLists.txt to ensure that la_constants.mod is
built before any other object or modulefile that depends on it.
