# This is the Makefile for EGL Gallium driver package.  The package consists of

#   egl_gallium.so - EGL driver
#   pipe_<HW>.so   - pipe drivers
#   st_<API>.so    - client API state trackers
#
# The following variables are examined
#
#   EGL_PLATFORMS       - platforms to support
#   GALLIUM_WINSYS_DIRS - pipe drivers to support
#   EGL_CLIENT_APIS     - state trackers to support
