Building Nim with Xmake

Nim compiles to C (or C++ / JavaScript) via nim c / nim cpp; xmake wraps this into a regular target model.

1. Minimal project

xmake create -l nim -t console hello
cd hello
xmake run

add_rules("mode.debug", "mode.release")

target("hello")
    set_kind("binary")
    add_files("src/*.nim")
