The warning you have are almost harmless, they said just that the MAIN application is built with an OSX sdk older than the libraries it uses. This can be a problem since the application will be able to run on macos 11 but the library may use some macos12 only symbols.
I usually build with 10.10 MACOSX_DEPLOYMENT_TARGET env variable, both the libraries (gtk, ffmpeg...) and the application. Please note that the C target (so most GTK APIs) has an ABI that is almost freezed, but if you use also C++ libraries (ie GTKmm) having libraries compiled against a newer SDK than the application may be a problem.
