This is not the right place. directfb-lua must be inserted in the Lua
modules section, just after 'dado'.

The dependency with Lua is implicit in the Lua modules section.
The dependency with DirectFB must be rewritten like this :

    select BR2_PACKAGE_DIRECTFB
    depends on BR2_TOOLCHAIN_HAS_THREADS # directfb
    depends on BR2_INSTALL_LIBSTDCPP # directfb

with this comment statement at the end of the file :

comment "directfb-lua needs a toolchain w/ C++, threads"
    depends on !BR2_TOOLCHAIN_HAS_THREADS || !BR2_INSTALL_LIBSTDCPP

Now, Buildroot has a Github helper.
DIRECTFB_LUA_SITE = $(call
github,ezequielgarcia,directfb-lua,$(DIRECTFB_LUA_VERSION))

> +DIRECTFB_LUA_LICENSE = MIT
> +DIRECTFB_LUA_LICENSE_FILES = COPYING

Now, Buildroot has various Lua interpreters, and directfb-lua could be
build with all of them.
DIRECTFB_LUA_DEPENDENCIES = directfb luainterpreter

At this time :
     INSTALL_DIR="$(TARGET_DIR)/usr/lib/lua/$(LUAINTERPRETER_ABIVER)"
