cmake build does not generate 64 bit build for windows.

[xpol]

cmake build does not generate 64 bit build for windows when luarocks installed with a 64 bit lua.

We need to add -DCMAKE_GENERATOR_PLATFORM=x64 to the command line.
I wonder why CMake does not do that by default.

@xpol could you try the fix I submitted here ?

[ignacio]

Meh, I'm not happy with this. To be able to use CMAKE_GENERATOR_PLATFORM=x64 we need to know if we're on Windows, using MSVC and Lua has been built as 64 bits.
When using makefiles, the above does not apply. I also don't know what happens when using Mingw.

Right now, I'm looking for a way to get cmake to report which compiler is going to use.

I'm back here again.
Today i tried the Windows 64 bit build for lua-rapidjson.

But it seems have issue when install busted.
Every depended module has no install error but it still reports the missing depends.

Missing dependencies for busted:
say >= 1.3-0
mediator_lua >= 1.1.1-0
penlight >= 1.3.2-2
luassert >= 1.7.8-0
dkjson >= 2.1.0
lua_cliargs >= 2.5-0
luasocket >= 2.0.1
lua-term >= 0.1-1
luafilesystem >= 1.5.0

Missing dependencies for penlight:
luafilesystem

See full build log here on appveyor.

I don't know exactly is this due to luarocks or busted or just my install_lua.bat has gone wrong.

This may not be a LuaRocks issue. It is CMake that it is using a newer Visual Studio version instead of the one you chose in appveyor. You need to choose the generator when building, and you should do that in your config.lua, by setting cmake_generator to the appropiate value.
This might be a nice addition to https://github.com/ignacio/lua-appveyor-example

I'm testing a fix for that.
