[Scons-users] Different variant_dir value in SConscript builder methods

[Dan Pidcock]

One way would be to pass the type of library (static/shared) into the
SConscript and call the SConscript four times with each possible variant,
changing your SConscript so that it builds one library of the correct type
each time. I don't think there's any particular SCons way of doing it, it's
up to you to find a way.
