If you're generating a cmake script, the generated file should contain this
line:

get_filename_component(SELF_DIR "${CMAKE_CURRENT_LIST_FILE}" PATH)

and then when you want to refer to a fully qualified path, construct the
path using the SELF_DIR variable, like so: "${SELF_DIR}/path/to/whatever"
You can post your generated cmake script if this still does not work.
