#New Module CMake Template written by Scott Nykl. This requires the engine is already built, compiled, and INSTALL'd to user land (.../repos/aburn/usr/).

#This simply includes the module-wide Google Test cmake script that all modules use
#to create a Test Project so Google Test can be used within a module.
#This CMake script is located in "..../usr/include/cmake/aftrModule_GTest_Proj.cmake"
