Actually, I don't think there is any IF(UNIX) stuff in the FIND stuff.  
However, I do think this might be the answer to our question about the
correct install path.  I think you have to do some special stuff to create
an MSYS executable, but just compiling within the MSYS environment does not
make a program aware of the /usr/local file system that MSYS creates.  So, I don't think
you would want to install programs into a directory that you could not find....
With cygwin, if you link with the cygwin runtime, your program automatically
knows about cygwin mount points, symlinks, etc because it gets a different libc.
However, with MSYS you link with the native Microsoft libraries and your program knows 
nothing about the special files that MSYS uses to simulate a UNIX file system.

Also, for cygwin, CMake defines UNIX as well as WIN32.
