Re: [PATCH 0/3] MR9222: fluidsynth: Invert relative to the max value instead of 1.0 in fluid_mod_transform_source_value().

[Michael Stefaniuc (＠mstefani)]

Hmm, I looked at the release notes for 2.4.3 and subsequent releases in 2.4.x and those don't mention the C++ requirement.
The build documentation https://github.com/FluidSynth/fluidsynth/wiki/BuildingWithCMake mentions
```
Starting with fluidsynth 2.5.0, a C++11 compliant compiler will be required.
