Thanks, your issue is that LUA_DLL is used as a c string so any backslashes need to be escaped. E.G. change it to @set LUA_DLL=C:\Program Files (x86)\Lua\5.1\lua5.1.dll

[daurnimator]

Thanks; anything you can do to avoid that?

Otherwise, I just noticed your "RELEASE" build does a debug link anyway

[jmckaskill]

Actually thinking about this a bit further, you shouldn't have to use the path at all. The LUA_DLL variable only needs to contain the lua dll name not the full path as the dll has to be on the PATH anyways. I'll check in a commit that further clarifies this.

As for release building debug, thats actually on purpose. The cl command line builds optimized code (/MD and /Ox) with debug info (/Zi). The link then has the /debug arg so that the pdb is generated to be able to debug the release exe. Note that as the debug info is in a separate file, this does not increase the size of the exe, but comes in very handy if you need to debug it.
