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.

Also replace OPLKLIB_DEBUG by OPLKLIB in OPLK_LINK_LIBRARIES macro
if CMAKE_BUILD_TYPE is "Debug", otherwise TARGET_LINK_LIBRARIES can't
find the openpowerlink library.

Fixes:
http://autobuild.buildroot.net/results/da4/da445b65cb136d71577f04e3a17fdb2ef6302a9b

This patch has not been accepted by upstream:
https://github.com/openPOWERLINK/openPOWERLINK_V2/pull/57

Add PCIe support (v2.3.2)
