It wasn’t an obvious journey figuring out that I had to download the live build stuff in order to enable compilation.
There’s no indication within the Projucer itself that you have to do this first, at least not until you dig around and hope to find something to trigger the download of the files.
As I mentioned, this was not obvious and I don’t believe this is as discoverable as it may seem. The Screwdriver + Wrench USSR button doesn’t explain what’s going on or why I should bother going there in the first place.
I still stand by my UX request of triggering the download of your DLL (or whatever file(s) needed) when the Build->Enable Compilation menu button is clicked.
