[Cmake] Modules/FindPythonLibs.cmake

[Ken Martin]

Hello Folk,

I have added registry support to the FIND_LIBRARY, FIND_PATH and
FIND_PROGRAM commands. See below ...

It could be if it also found the python executable. I've been keeping
the searches for runtime programs separate from the development
support. So that someone who needs to run Python wouldn't necc. get
CMake variables for all the libraries/includes etc. It seems that many
builds need to use tools like Python as part of the build process but
aren't actually compiling against python. I'm trying to isolate those
users from seeing all the other values.

It is implemented and at least slightly tested.

The regexp is \[(HKEY[A-Za-z_0-9\.\\]*)\] so I'm basically looking for
[HKEY I don't think there is any need for a special word.
