Since there is nothing platform specific in the code of WindowsManifest it'd make sense to build it on any OS; At the very least for cross compile setups.

I sadly am not very accustomed to Macs so I don't know the details, but I don't think this patch would change anything about your situation.

Could it maybe be related to the `CMAKE_OSX_SYSROOT` variable somehow? CMake seems to use it to lookup packages from the platform SDK.
