# Using dynamic linked lua is not recommended for performance

# Mainly, this is of concern if your arch is poor with GPRs, like x86
# Note that this only affects the interpreter binary (named lua), not the lua
# compiler (built statically) nor the lua libraries.
# A slotted Lua uses different directories for headers & names for
# libraries, and pkgconfig should reflect that.
