Thanks for all that.
Seems I got misled by reading the front page of the resynthesizer github, which does only give flathub as the location for a pre-build for linux, so I downloaded the source and read its INSTALL file which explains the Makefile conventions and says nothing about meson. I missed the link on the github page to "build from source" since I'd already found the provided (incorrect) instructions to build from source. Ho hum.
