Maybe. You clearly have an ARM install of glib but your build seems to need an 
Intel install for some reason. You need to find out why. What platform are you 
compiling on? What did CMake tell you it found for GLib2 when you ran “make 
-Denable-framework=off ..”? Here’s what it told me:

cmake -Denable-framework=off ..
-- The C compiler identification is AppleClang 15.0.0.15000309
-- The CXX compiler identification is AppleClang 15.0.0.15000309
...
-- Found GLib2: /opt/homebrew/Cellar/glib/2.80.0_2/lib/libglib-2.0.dylib (found 
suitable version "2.80.0", minimum required is "2.6.5")

During compilation in a clean “build” directory, I get several warnings, but 
the “Linking CXX shared library libfluidsynth.dylib” completes without error.

It is possible you are using a compile chain that is actually generating Intel 
binary. I would check to make sure CMake is seeing the right compiler. Also, 
note that brew comes in two versions which are incompatible, one for ARM and 
one for Intel. You can install both on your system if you want, and the Intel 
executables will be run in Apple’s emulator which is quite fast and perhaps 
even usable for audio processing.
