[CMake] Can't configure Perl on Windows

[Tron Thomas]

Okay, so even though CMake succeeded on my system without setting 
CMAKE_PREFIX_PATH, I set it anyway.  I then deleted all the CMake 
generated file, and ran CMake again.  This time CMake said that it found 
Perl in the location I wanted CMake to find it, and the build 
configuration succeeded.  I'm hoping this proves my configuration will 
work without Cygwin.
