[cmake-developers] cmake -E capabilities

[Tobias Hunger]

Hello Developers,

https://github.com/hunger/CMake/commits/cmake-capabilities

is in a state now that could use another review.

It addresses all the issues that Stephen brought up, with small patches
extending the information reported via GeneratorInfo bit by bit. Only
when all that is in place, the new cmake -E capabilities is added.

This now creates extra generators (all of them), which does not seem to effect
run time of cmake -E capabilities by much on Linux. I have not tested this on
Windows/Mac though as I do not have those platforms handy.

If that is not acceptable, then some string-parsing is going to be necessary.
I'd move that into cmake::GetRegisteredGenerators, where it is more of an
implementation detail than in the code that actually handles the capability
reporting.

Best Regards,
Tobias
