# It sets the following variables which are used by the master Makefile
# after the call:
#
#   BASE_OBJ_S:   The single-object base layer.
#   BASE_OBJ_M:   A list of all objects for a multiple-objects build.
#   BASE_EXT_OBJ: A list of base layer extensions, i.e., components found
#                 in `freetype/src/base' which are not compiled within the
#                 base layer proper.
#
# BASE_H is defined in freetype.mk to simplify the dependency rules.

#   compiled as a single object file using ftbase.c).
