Possibly that's both (colors, line clearing) related to ANSI color escape codes
as used by the native build tool.
It's perhaps possible to analyze where exactly the augmented output gets
lost within the chain (doing analysis on source code side, of course).
Probably some CMake handling or adopting of tool output filters out that markup.

Yes, very much so. Dito for ninja and make here (and as launched by
some cross-platform [ruby/python/perl] script).
Somehow I failed to actively pick up that I could go through cmake --build .
rather than grabbing ${CMAKE_BUILD_TOOL} (formerly ${CMAKE_MAKE_PROGRAM})
directly.
Also, one might want to pass e.g. parallelization (make -jX) configuration
through it
as well, so it might be useful to devise a standard parameterization
mechanism for --build to support *any* such attributes, in a generalized form.
