Old C Interface unittests are commented out

[cadop]

CMake config comments out c_interface tests:

dhart/src/CMakeLists.txt

Lines 416 to 422 in 8aa1655

	# ${C_TEST_DRIVER_DIR}/embree_raytracer_cinterface.cpp
	# ${C_TEST_DRIVER_DIR}/objloader_cinterface.cpp
	# ${C_TEST_DRIVER_DIR}/analysis_C_cinterface.cpp
	# ${C_TEST_DRIVER_DIR}/pathfinder_C_cinterface.cpp
	# ${C_TEST_DRIVER_DIR}/view_analysis_cinterface.cpp
	# ${C_TEST_DRIVER_DIR}/visibility_graph_cinterface.cpp
	# ${C_TEST_DRIVER_DIR}/spatialstructures_C_cinterface.cpp

Need to look back and find when this happened and if all tests are covered by other ones, as the interface seems to be an older version:

dhart/src/Cpp/tests/src/embree_raytracer_cinterface.cpp

Line 45 in 8aa1655

status = LoadOBJ(obj_path_str.c_str(), obj_length, rot[0], rot[1], rot[2], &loaded_obj);
