[cmake-developers] Generalized verbose option for cmake --build.

[Ray Donnelly]

Hi CMake developers,

Why do I need to know the necessary verbose flag to make each back-end
that cmake --build calls emit more information? If forces my build
script to switch on the platform in a really ugly way for something
I'd consider a very important feature (you already hardcode various
things to enable cmake --build to work, so why not this as well?)
Something like cmake --build --verbose would be good.


Best regards,

Ray.

There is work on that here:

but it has stalled.

I had the same problem with our automated builds, and I solved this by simply
passing

-D CMAKE_VERBOSE_MAKEFILE=On

to the CMake run.
