# Provide a set of makefile variables to which we can attach lists of object
# files, libraries to link against, preprocessor and linker options, etc. The
# prefixes tell us to which targets the variables apply:
#
# Shared lists:
#  COMMON_ - objects common to all five targets
#  CL_     - objects common to the four client targets (NQ, QW, SW & GL)
#  SV_     - objects common to the three server targets (NQ SW&GL, QWSV)
#  NQCL_   - objects common to the NQ client targets (SW & GL)
#  QWCL_   - objects common to the QW client targets (SW & GL)
#  QW_     - objects common to the QW targets (CL & SV)
#  SW_     - objects common to the software rendering clients
#  GL_     - objects common to the OpenGL rendering clients
#
# Target specific lists:
#  NQSW_
#  NQGL_
#  QWSW_
#  QWGL_
#  QWSV_
#
# The suffix describes where the list is used
#  _OBJS     - list of object files used as dependency and for linker
#  _LIBS     - list of libs to pass to the linker
#  _CPPFLAGS - C preprocessor flags, e.g. include directories or defines
#  _LFLAGS   - linker flags, e.g. library directories
#
# Then we have configuration options which will alter the content of the lists:
# - VID_TARGET  - video driver
# - IN_TARGET   - input driver (usually tied to video driver)
# - CD_TARGET   - cd audio driver
# - SND_TARGET  - sound driver
# - USE_X86_ASM - conditionally replace C code with assembly
#
#
# 1. Set up lists of object files which aren't affected by config options
# 2. Go through the various config options and append to the appropriate lists
#
#
# TODO: Think about different groupings?
#       e.g. SW_RENDER_OBJS, GL_RENDER_OBJS, NET_DRIVER_OBJS...
