BUILDING_NODE_EXTENSION missing

[computerquip-streamlabs]

Because apparently, node requires this be defined on a target in order to properly provide linkage to a node module.

Sorry for the slow progress on this, I've been busy. You can manually add this by calling target_compile_definitions(<MODULE_TARGET_NAME> PRIVATE BUILDING_NODE_EXTENSION=1). I'll make sure this is in the next release.
