[CMake] Calling of find_package from function

[Andrey Upadyshev]

I've solved my problem with special macroses. First saves all non-cache
variables (have to be called at the beginning of the function) and second
one propagates all the changed/added variables to the parent scope (have to
be called of at end of the function). If someone interested in code, it's
