# src/gallium/targets/egl-static/Makefile
#
# This is Makefile for egl_gallium.so.  It is static in that all state trackers
# and pipe drivers are linked statically when possible.
#
# The following variables are examined
#
#   EGL_PLATFORMS       - platforms to support
#   EGL_CLIENT_APIS     - state trackers to support
#   GALLIUM_WINSYS_DIRS - pipe drivers to support
#   SHARED_GLAPI        - st/mesa can be statically linked or not
#
