CMake-MinGW support is much better than I realized just yesterday.  I'm
compiling in cygwin using the cygwin installed version of gcc and the
-mno-cygwin option to use MinGW.  I guess you could be using MinGW outside
of Cygwin, which could be different.  According to Bill Hoffman's posts to
the CMake mailing list the key is to use the Windows version of CMake and to
generate Unix Makefiles.

The configuration commands I'm using now are below.  vcl/testlib/vpl/vsl/vbl
and some other core libs compile fine.  vil/vnl will need tweaks for MinGW.
I'm looking into this myself, but can't make any guarantees.  At a glance
some problems have to do with IO and isnan().
