Building qtlua: ‘LUA_PATHSEP’ was not declared in this scope

[NataliaDiaz]

Is there any alternative to fix the install of qtlua without going backwards and doing:
TORCH_LUA_VERSION=LUA51 ./install.sh
instead of
TORCH_LUA_VERSION=LUA52 ./install.sh
?
Issue described here: facebookarchive/torchnet#84 :

When doing make in first installation options in https://github.com/LuaDist/qtlua
I get:
