[CMake] Error using cygwin with Matlab2007a installed

[David Cole]

What happens if you type "gmake --help" or "which gmake" from the same
prompt...?

CMake should just use the PATH env variable to find the right gmake
first. If not there, it may look in some other well known places, but
if there is one in your PATH, it will use it...

Most likely considered a feature. :-)
