Missing icon: ...failed to load (MacOS, make update, make)

`/blender-build/build_darwin/bin/blender.app/Contents/Resources/2.80/datafiles/icons/ops.gpencil.stroke_cutter.dat Unable to load from file

Confirmed. It’s not there. Suggestions on how to troubleshoot? Assuming CMake issue? Perhaps issue with “make update”?

FollowUp:

make clear
make
