Introduced mandatory call to project in top level CMakeLists.txt

Browse Source 
Somehow this was never called in the OPM modules. But the CMake documentation
actually says:
"The top-level ``CMakeLists.txt`` file for a project must contain a
literal, direct call to the ``project()`` command; loading one
through the ``include()`` command is not sufficient.  If no such
call exists CMake will implicitly add one to the top that enables the
default languages (``C`` and ``CXX``).
"

Without it some variables (like CMAKE_PROJECT_NAME) are not correctly defined.
