[Cmake] Upper case for package names

Sounds interesting, but... doesn't this command needs to be compiled, somehow, 
before using it. So, can it be part of my source tree and be compiled 
automatically by CMake before it's used in the same build?

I want to set them.
I'm trying to setup a build framework which is a little bit more complicated. 
My CMake project consists of several "packages" which can be either compiled 
as part of the project or used from a prebuilt source. I want to use the 
FIND_PACKAGE mechanism to setup the proper INCLUDE_DIRs and LINK_DIRs (so the 
package can be used stand-alone, too).
As in my main CMakeList, I already know where to look for the 
<pkg>Config.cmake file, I wanted to preset the _DIR cache entry 
automatically.
