[bug] Incomplete CMake build-helper documentation

[Adnn]

Currently, CMake build helper doc states:

CONAN_COMPILER: Conan internal variable to check the compiler

Is it taken from the self.settings.compiler setting? If so, should it appear there (as it seems to appear for most other definitions when they are taken from a setting).

Also, CONAN_COMPILER_VERSION might be missing from this list.

Thanks for the report. Yes, this could be missing from the docs. I am moving this issue to the documentation repo to track it better.

@danimtb Thank you for correctly re-routing this issue!
