Env:
Windows 21H2 19044.1889
Python 3.10.7
scons 4.4.0
Mingw-w64 11.2.0
Compiling "godot-cpp", an error :
g++: fatal error: cannot execute 'cc1plus': CreateProcess: No such file or directory

Simple repair
SConstruct add:
env.Append(ENV = os.environ)

But I'm godot rookie
I don't know which code caused the error
