support for downstream apps inconsistent between autotools and CMake builds

The moab.make.in and MOABConfig.cmake.in contain substantially different sets of functionality. The latter is mostly consistent with MOABConfig.cmake.cmake.

Thus, there is (growing) consistency for downstream apps that rely on CMake, regardless of how MOAB is built.
