For some reason CMake seems to be really good at finding Cygwin's Python
instead of the python.org Python even though c:\Python27 comes before
c:\cygwin\bin in PATH on the Windows builders. The problem is that
Cygwin's python.exe is a symlink, which doesn't work too well when
called outside Cygwin:

As part of yesterday's "upgrade all copies of Bash everywhere"[1]
exercise I upgraded all of the Cygwin packages on the Windows builders.
This included a Python upgrade, which is required by AsciiDoc. I'll see
if I can force CMake to find the right executable using
-DPYTHON_EXECUTABLE but it would be nice if it could figure things out
on its own.


[1] If have Bash installed anywhere, drop what you're doing and upgrade
it now. http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2014-6271
