Can't build Slicer CTK component (Mac 10.12, Qt 5.9)

I’m currently unable to build the newest master branch Slicer. It’s failing at the CTK target. I can see in my CMake configuration that the value of Qt5Network_DIR is defined, but when Xcode attempts to build the CTK target within the CTK project, I get an error message that Qt5NetworkConfig.cmake can’t be found. How can I fix or work around this? Thanks.
