A premake5 script for building assimp

assimp.lua

-- How to use:
-- 0. Get assimp from https://github.com/assimp/assimp
-- 1. Place this file next to the cloned assimp repository like this:
--
--       assimp.lua
--       assimp/
--
-- 2. Set up configuration headers
--
--     2.1 Create a folder for configuration headers, I usually name it _config_headers/
--
--          _config_headers/assimp/     <- config.h will be included as "assimp/config.h" so the assimp/ part is important
--          assimp.lua
--          assimp
--
--     2.2 Generate config.h and revision.h from assimp/code/config.h.in and assimp/revision.h.in and put them into _config_headers/assimp. (You can also just edit and rename them, that's what I usually end up doing.)
--
--          _config_headers/
--            assimp/
--              config.h
--              revision.h
--          assimp.lua
--          assimp
--
-- 3. Edit the 'files { ... }' and 'defines { ... }' depending on which importers/exporters you need. By default I enabled COLLADA, OBJ, FBX and ASSBIN (assimp binary, good for caching)

First of all, thank you @Cannedfood for making this much easier for me!

I've updated it to work with latest pull assimp, files have just been moved basically and new dependencies added. Only tested it working with FBX and Obj currently, use the above but replace files and includedirs with the following

files {
	-- Dependencies
	'assimp/contrib/unzip/**',
	'assimp/contrib/irrXML/**',
	'assimp/contrib/zlib/*',
	-- Common
	'assimp/code/Common/**',
	'assimp/code/PostProcessing/**',
	'assimp/code/Material/**',
	'assimp/code/CApi/**',
	'assimp/code/Geometry/**',
	-- Importers
	'assimp/code/AssetLib/IQM/**',
	'assimp/code/AssetLib/Assbin/**',

	'assimp/code/AssetLib/Collada/**',
	'assimp/code/AssetLib/Obj/**',
	-- 'assimp/code/AssetLib/Blender/**', 'assimp/contrib/poly2tri/poly2tri/**',
	'assimp/code/AssetLib/FBX/**',
	-- 'assimp/code/glTF2/**',
	-- 'assimp/code/glTF/**',
	'assimp/code/Assbin/**' -- For caching
}

includedirs {
	'_config_headers/',
	'_config_headers/assimp/',
	'assimp/',
	'assimp/contrib/',
	'assimp/contrib/irrXML/',
	'assimp/contrib/unzip/',
	'assimp/contrib/rapidjson/include/',
	'assimp/contrib/pugixml/src/',
	'assimp/contrib/zlib/',
	'assimp/contrib/utf8cpp/source',
	'assimp/code',
	'assimp/include',
}

Thank you very much @Karamu98! I updated the gist accordingly.
