Subject: [PATCH] Add top level CMakeLists.txt

This CMakeLists.txt can be used to build openpowerlink
using a automated build system.

Don't use FIND_LIBRARY when the stack is built from a top
level build (ie CFG_OPLK_LIB is ON).
For a top level build, CMake will automatically add a build
dependency on oplk libraries for building demos applications.

This patch has been submitted upstream:
https://github.com/openPOWERLINK/openPOWERLINK_V2/pull/57
