The problem is not with the platform, it's with how the flags are passed to the underlying compiler (nvcc). Position independent code is not specific to Windows. Just set the POSITION_INDEPENDENT_CODE property to ON for the relevant target, or set the global CMAKE_POSITION_INDEPENDENT_CODE. CMake will know not to add the -fPIC flag when nvcc is invoked versus when the native build tool is invoked.
