A general note:

We do not want to run the auto-detection when *_DIR is NO_BUILD. To run the auto-detection, leave this variable blank. NO_BUILD is reserved for cases where the library is known to be found by means opaque to the configure script (e.g. MPI that is always present on Crays).

There was a discussion about this in Trac, and we initially and erroneously agreed that running the auto-detection would be a good idea. It turns out it wasn't (it broke the build on several systems), and thus we reverted this change.
