Hi, Peter!
Sure, I can show you how I've used it exactly. Here it is:
set ( kofile ${CMAKE_CURRENT_SOURCE_DIR}/manager.ko )
add_custom_command ( OUTPUT ${kofile}
COMMAND ${kbuild_cmd}
WORKING_DIRECTORY ${CMAKE_CURRENT_SOURCE_DIR}
DEPENDS ${src} Kbuild )
add_custom_target ( cool_driver ALL DEPENDS ${kofile} )

Hi,
could you post the working example? I'm doing something similar but
I'm doing it wrong, the add_custom_command is always being build in my
case.
Thanks in advance,
Peter.
