In that case you can use DESTDIR and TARGET. But ensure you use OUT_PWD so you ensure that your get the proper build folder to store the build artefact.

@Wieland Thanks for the reference - that has worked for me.

Also, thanks for the Qbs information - i hadn't seen this before but will look into it

@SGaist - thanks for the info

I had previously tried something similar but I think it may have been the escaping of quotes which caught me out.

AFAIK, no.

However I'd recommend to rather have a comms.pri file that you include in your application .pro file that will do that.
