Usage: cmake -DWARN_MODE=early|late|both

Warn modes:

  early   print warnings while compiling each source file (like usually)

  late    print warnings at finish of build process

  both    print warnings both 'early' and 'late'

Suppressing specific warnings. All messages with 'warning:' and 'note:'

are collected in <build_dir>/compile.warnings To make them all suppressed do

  cd <build_dir>; cat compile.warnings >> suppress.warnings

After that only newly introduced warnings will be shown. This helps to

concentrate on current task's warnings effectively avoiding those that are to

be fixed by other people.

To disable processing warnings by this module do

  cmake -UWARN_MODE
