Merge branch 'cmakeBuild' into develop (PR #230)

This merge introduces a CMake build capability to complement the CMake build in
WRF. Building the WPS with CMake requires that WRF was also compiled with CMake
(provided the geogrid and metgrid programs are to be built).

The WPS CMake build follows the same procedure as the WRF build procedure, using
the following:

   ./configure_new
   ./compile_new

The prompts will look similar and present the user with available options
specific to their system.
