This is a complete stab in the dark, but I wonder if your clang (Xcode tools…)
needs reactivation. I know some people have reported that they’ve needed to
re-accept the license and/or reinstall the Xcode tools following the upgrade.
Again, this is just a wild guess.

Some recent configuration change (either upgrading to Sierra or CMake 3.5.0)
has prompted the following warning when running Cmake on a particular project:
CMake Error in /CMakeLists.txt:
No known features for CXX compiler
"Clang"
version 3.5.0.
