CMakeLists.txt for gmock uses gtest_SOURCE_DIR for setting the include paths. When using fetch content with the name "GTest", the value of gtest_SOURCE_DIR is updated to the repository root instead of the googletest subdirectory. As a result, gmock will fail to compile due to invalid include paths.
This can be fixed by not relying on gtest_SOURCE_DIR but reading the include directories from the gtest target.
It used to work for other compilers because gmock depends on gtest (using target_link_libraries). So gmock had the broken include paths from gtest_SOURCE_DIR plus the working paths from the target. For MSVC, gmock does not depend on gtest.
