This hxcpp fork was previously used for the Android and iOS ports I provided. Although it is no longer used for those ports, it is still maintained and continues to exist for the Shadow Engine.
For Lime:
haxelib run lime rebuild hxcpp
Otherwise:
cd "$(haxelib libpath hxcpp)/tools/run"
haxe compile.hxml
cd "$(haxelib libpath hxcpp)/tools/hxcpp"
haxe compile.hxml
