It == "lib is automatically appended".

The PATH_SUFFIXES are added to all of them. ok, I now have: find_path(VAR header.h HINTS /opt/p1 PATHS /opt/p2 PATH_SUFFIXES foo) This would search in /usr/include, /usr/foo, /opt/p1/foo, /opt/p2/foo, but neither in /opt/p1/include nor /opt/p2/include. Correct? Eike
