[CMake] Building linux kernel module with Cmake

[suhasj at aftek.com]

Oops I missed the main statements...
Sorry for that

Contibuing to the previous post ...

ADD_CUSTOM_COMMAND(OUTPUT DRIVER_BIN_FILE
                   COMMAND ${KBUILD_CMD}
                   DEPENDS ${MODULE_SOURCE_FILES} VERBATIM
                   )

ADD_CUSTOM_TARGET(driver
                   DEPENDS ALL DRIVER_BIN_FILE )


> Well there's no ADD_CUSTOM_COMMAND or ADD_CUSTOM_TARGET for one thing.
