[CMake] Building linux kernel module with Cmake

[Suhas Jain]

As you said I am using these ADD_CUSTOM_COMMAND / ADD_CUSTOM_TARGET
But its not working at my end... please help me out
This is what I have in my CMakeLists.txt file
===========================================================================
Set( MODULE_OUTPUT_FILES    hello.o
                            hello.mod.c
                            hello.mod.o
                            hello.ko
                            .hello.o.cmd
                            .hello.ko.cmd
                            .hello.mod.o.cmd
				    main.o
				    .main.o.cmd
				    output.o
				    output.o.cmd
                            .tmp_versions/hello.mod
                            .tmp_versions/ )

Set( MODULE_SOURCE_FILES    output.c 
				    main.c )

Set( DRIVER_FILE        hello.ko )
Set( DRIVER_TARGET_NAME hello-module )
Set( DRIVER_BIN_FILE    ${CMAKE_BINARY_DIR}/bin/${DRIVER_FILE} )
Set( MODULE_SOURCE_DIR  ${CMAKE_CURRENT_BINARY_DIR} )

Set( KERNEL_DIR "/lib/modules/2.6.20-16-generic/build" )
Set( KBUILD_CMD ${CMAKE_MAKE_PROGRAM}
                -C ${KERNEL_DIR}
                M=${MODULE_SOURCE_DIR}
                modules )
=========================================================================

Please point me out if I am doing something wrong. I think I am missing
something to add.

It would be simpler to use ADD_CUSTOM_COMMAND / ADD_CUSTOM_TARGET to
invoke the Linux kernel's native Kbuild, then utilize the results.
