Hi,
When Buckminster performs a headless build on a Linux x86_64 machine
against a target platform that contains the RCP delta pack, the default
windowing system is always set to "motif". This causes the build to fail
since no such combination exists. While we do provide means to
explicitly set the targetWS, we would still like to set defaults that
corresponds to existing combinations so that the user typically doesn't
have to specify an explicit windowing platform. My question is, where
are these defaults picked up today and how can I specify other defaults?
