FindOpenSSL.cmake - ours vs. the cmake one

[Alexander Neundorf]

Hi,

I'm still in the process of merging our stuff, e.g. Find-modules from kdelibs,  
into cmake.
Now, attached are the current FindOpenSSL.cmake from CMake and the one from 
kdelibs.
Especially under Windows they do quite different things.

Can somebody else please have a look at the two files and let me know whether 
anything from our version has to be merged into the one from cmake or whether 
the one from CMake is good enough as it is ?

Alex
