On macOS, Core has plugins that link against CorePrivate. In a non-prefix build, user projects failed on find_package(Qt6 REQUIRED COMPONENTS Core), because CorePrivate is required for these plugins in a non-prefix build, but it's not automatically pulled in. This is only an issue for CMake < 3.26, because these older CMake versions lack the BUILD_LOCAL_INTERFACE generator expression. Fix this by pulling in the private modules for non-prefix builds when using CMake < 3.26. Also, issue a warning in this situation.
