CMakeProjectManager: Fix findCMakeNode function

Browse Source 
Via CMake project we can add subdirectory like:

> add_subdirectory("subdir/subsubdir" "enotherdir")

Where "subdir" my not contain "CMakeLists.txt" file.

And intermediate directory can contain CMakeLists.txt file
that is not a part of the root node.

This change fix it.
