Leadwerks and Premake


reepblue

Premake is multiplication project maker.Unlike CMake, it simply generates a project file for the given IDE giving you a clean result. You only need the one light weight executable and a lua script for this to work.  I've spent today setting it up with Leadwerks. I haven't tested Linux yet, but it should work.

My premake5.lua file:

g_LeadwerksHeaderPath = "./Engine/Include"
g_LeadwerksLibPath = "./Engine/Libs"

function GlobalSettings()
	-- Include Directories
	includedirs
	{
		"%{prj.name}",
		"%{g_LeadwerksHeaderPath}",
		"%{g_LeadwerksHeaderPath}/Libraries/SDL2-2.0.10/include",

	description = "Builds the stock lua app",
	execute = GenerateLuaApp()
 }

 if _ACTION == "luaapp" then
	GenerateLuaApp()
 end

Then I just have batch file that builds the project file.

"devtools/premake5.exe" vs2017 luaapp

My impressions are more positive on this than CMake as CMake creates a lot of extra files to do real time updating if the CMakeList file is updated. Premake simply just builds the project file and that's it. It really reminds me of VPC stuff I had to deal with in my modding days. Really interested to how codelite projects generate on Linux.
