Subject: [PATCH] Fix fallback finding of ccd

Fix finding include directory for ccd when falling back from using
pkg-config. The old mechanism would find the include directory as e.g.
`prefix/include/ccd`, which fails when we try to include `ccd/ccd.h`.
Drop the path suffix and instead search for the literal name
`ccd/ccd.h`, which will produce the correct include path.
