+Subject: [PATCH] Fix sdrpp breaking every time the package is rebuilt.
+
+On NixOS, the INSTALL_PREFIX changes on every rebuild to the package, but sdrpp
+fills it in as part of the default config and then installs that config
+to the users home folder. Fix this by not substituting @INSTALL_PREFIX@ in the
+default config until runtime.
