Make build system usable as a git submodule
Replace CMAKE_SOURCE_DIR/CMAKE_BINARY_DIR with PROJECT_SOURCE_DIR/
PROJECT_BINARY_DIR so paths resolve correctly from add_subdirectory().
Guard global settings (CMAKE_CXX_STANDARD, CMAKE_BUILD_RPATH,
qt_standard_project_setup, demo) behind PROJECT_IS_TOP_LEVEL.
Export OPEN62541_INSTALL_DIR and QTOPCUA_INSTALL_DIR as CACHE INTERNAL
so parent projects can set up RPATH and plugin paths.
