Merge branch 'atmosphere/cmake_framework' into develop (PR #1366)

This merge fixes a CMake build failure by adding src/framework to the list of
include file search paths.

With merge commit 55c737f (PR #1359), the file mpas_halo_interface.inc from the
src/framework directory was included by several files in the atmosphere core via
preprocessing directives.  While the Makefile files under src/core_atmosphere
already contained the framework directory in the list of search paths for
include files, the CMakeLists.txt files did not, resulting in a build failure
when compiling the atmosphere core with CMake.

To address the build error, the CMakeLists.txt file for src/framework now
exports its source directory as an interface include directory, adding that
directory to the compilation include path for any target that links against
framework.
