OK, thanks, I now understand what's going on. I misunderstood what was
happening - I didn't realise that if a value was already in the cache
then the *first* FIND_PATH is ignored as well. It's been so long since
I changed my setup that I'd forgotten this. If I clear the cache then
I can indeed find the stuff in /usr/local preferentially.

However, this is a pain - I'd rather have cmake reconstruct the cached
FIND_PATH values each time I run it, without my having to remove it
or alter it manually - is that possible ?
