find_library(IOMP5_LIB iomp5 PATHS /opt/intel/...
                             ^^^^^

find_library(IOMP5_LIB iomp5 PATHS /opt/intel/...
                             ^^^^^

The correct option to specify hard-coded search paths for the find
functions is "PATHS". Apparently, FIND_LIBRARY() is tangled if you
say "PATH" instead, so the following PATH_SUFFIXES doesn't work as
expected.
