[Arch Linux][AUR Package] Compilation error: assignment of read-only member in RapidJSON

[kiy-00]

Description

When building a Cocos2d-x C++ project on Arch Linux using the AUR package cocos2d-x-src (version 3.17.2-1), the compilation fails due to an assignment of a read-only member in the RapidJSON library.

Steps to Reproduce

1. Install the cocos2d-x-src package from AUR:

yay -S cocos2d-x-src

2. Create a new Cocos2d-x project:

cocos new MyGame -p com.example.mygame -l cpp
cd MyGame

3. Attempt to build the project:

 cocos run -p linux
