Comment (by robe):

 I think GEOS detection needs some work. It doesn't like my GEOS 3.5.0 yet
 it does find it.

 I tried swithching to my GEOS 3.4.2 build and it didn't like that either:

 I'm building under mingw64-w64 and I built GEOS with CMake.  The others it
 detected correctly I built using standard autotools chain.
