# BOARD_GPU_DRIVERS should be defined.  The valid values are
#
#   classic drivers: i915, i965
#   gallium drivers: i915g, r300g, r600g, nouveau, vmwgfx
#
# The main target is libGLES_mesa.  Classic drivers depend on
#
#   libmesa_egl
#   libmesa_egl_dri2
#
# Gallium drivers depend on
#
#   libmesa_egl
#   libmesa_st_egl
#   libmesa_st_mesa
#   libmesa_glsl
#   libmesa_glsl_utils
#   libmesa_pipe_<DRIVER>
#   libmesa_winsys_<DRIVER>
#   libmesa_gallium
#
# The rules can be found in src/gallium/targets/Android.mk.
#
# For each classic driver enabled, a DRI module will be built.  It consits of
#
#   libmesa_dricore
#   libmesa_glsl
#   libmesa_glsl_utils
#   <driver-specific objects>
