Neither am I. For me it acts as a cygwin replacement, so I did what I
would have done there. (Installing stuff to /usr/local). I don't know
whether that's common practice among MSYS users, as I discovered MSYS
just recently.

Nice. That did the trick.  Even better, I can specifiy the path as
/usr/local/include and /usr/local/lib and cmake will convert it to the
proper Windows path all by itself.

In fact, configure based builds also required me to set CFLAGS and
LDFLAGS to point to these directories, so I don't think there is
anything wrong with cmake here. I just didn't know the proper spell to
make it work.

With that in mind, I don't think it would be appropriate to make a
feature request just now. If I run into more serious problems further
down the road I might reconsider, but at present I'm happy with this
solution :-). Thanks Brad!
