From AI:

If you are developing or maintaining software that uses app_indicator_new, consider updating your code to use libayatana-appindicator-glib.

Solution since March is add

target_compile_options(${TARGET} PRIVATE -Wno-error=deprecated-declarations) # Allow deprecated warnings

Could you fix this so I don't have to fork?
