On Windows, if you are using msys2, use Release mode when you do not 
actually need the Debug build.

The Debug build creates slower binaries, and more annoying *very large* 
files.

use -DBUILD_SMALL_DEBUG_FILES=ON option on msys2 to build Debug versions.

On my computer (not very fast), link process takes one minute in Release 
mode, and no QA build.
