Issue when building with Windows

[saspivey98]

Building lua-zlib on windows 10

Building zlib using cmake on VS dev

using luarocks to install

I believe the issue lies withing the rockspec. Looking at the 1.2-2.rockspec

When replacing lines 37-41 of the rockspec with

platforms = { windows = { variables = { LUA_LIBRARIES = "$(LUA_LIBDIR)/$(LUALIB)" }}},

it fixes the build issue on windows.

I am unsure if this is an issue from my end (or even the correct fix), but wanted to mention I noticed this when building.

From what I could tell when I faced this issue, the build tried to pass the full zlib dll path as -l argument to gcc, but it should only pass the library name (without path or extension) in -l and pass the path in -L. In addition, the dll on my local build was zlib1.dll and so the library name should be zlib1 and not zlib.
