   2 # LuaRocks package infrastructure
   3 # see http://luarocks.org/
   4 #
   5 # This file implements an infrastructure that eases development of
   6 # package .mk files for LuaRocks packages.
   7 # LuaRocks supports various build.type : builtin, make, cmake.
   8 # This luarocks infrastructure supports only the builtin mode,
   9 # the make & cmake modes could be directly handled by generic & cmake infrastructure.
  10 #
  11 # See the Buildroot documentation for details on the usage of this
  12 # infrastructure
  13 #
  14 # In terms of implementation, this LuaRocks infrastructure requires
  15 # the .mk file to only specify metadata information about the
  16 # package: name, version, etc.

  21 # inner-luarocks-package -- defines how the configuration, compilation and
  22 # installation of a LuaRocks package should be done, implements a few hooks to
  23 # tune the build process and calls the generic package infrastructure to
  24 # generate the necessary make targets
  25 #
  26 #  argument 1 is the lowercase package name
  27 #  argument 2 is the uppercase package name, including a HOST_ prefix
  28 #             for host packages
  29 #  argument 3 is the uppercase package name, without the HOST_ prefix
  30 #             for host packages
  31 #  argument 4 is the type (target or host)
