Fix a couple of issues with the CMake script

Summary:
The first issue is that I was missing a `G` in `LIBGFLAGS_INCLUDE_DIR` meaning that it always claimed it couldn't find gflags even though it did, and worked just fine anyways.
The second issue is that it was passing `/permissive-` to MSVC 2015 builds, even though MSVC 2015 doesn't support the permissive flag.
