[CMake] How to suppress output like "-- Checking whether C ", etc.?

[Andreas Pakulat]

Hi,

you can't tell cmake to do this and usually you don't want to either.
These are status messages indicating what cmake is using so you can
easily spot if cmake chose the wrong compiler or found a library in a
place where you didn't expect it.

To suppress all non-error output you can do:

cmake ../ >/dev/null

on *nix systems. That way only errors in your cmake files are being shown.
