Subject: autoconf: Configurable demos directories
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=8e4d14743035ba59b16e5c84246916f43487d455;p=mesa.git

autoconf: Configurable demos directories

The user can request specific demos directories to build in. For
example:

    ./configure --with-demos="demos,xdemos"

The drawback is that we don't check for the necessary libararies in
that case, only that the directory in progs/ exists.
