Just some notes:
You don't need to list all these search directories explicitely, most of them 
are searched by default. Have a look at Modules/Platform/UnixPaths.cmake.
Also instead of having a version with and one without "IL" you can use the 
PATH_SUFFIXES option for FIND_PATH()

In the end you can (should) use the find_package_handle_standard_args() macro 
which comes with cmake >= 2.6.0 to have the standard argument handling.
