[C API] Compilation issues with flatbuffers - with solutions

[Jack121298]

System Information Please provide the following information about your system:

• Steam Audio version: 4.5.3
• (If applicable) Unity version: N/A
• (If applicable) Unreal Engine version: N/A
• (If applicable) FMOD Studio version: N/A
• Operating System and version: Arch
• (Optional) CPU architecture (e.g. x86-64, armv7): x86-64

Following guide to build steam-audio, I get errors with flatbuffers.

1st error: "C++ versions less than C++14 are not supported."

2nd error: flatbuffers requires > C++ 17

3rd error: -Werror=stringop-overflow warning thrown as error when building flatpacks with gcc version 14.1. Similar issue seen here

Solutions All issues can be fixed by adding these flags into dependencies.json for flatpacks

"-DCMAKE_CXX_STANDARD=17", "-DCMAKE_CXX_FLAGS=-Wno-stringop-overflow"

I'd love to make a pull request but it is something I've never done before. Let me know if I can!
