Issue description
I am trying to install GDExtension for my godot, i am following the https://docs.godotengine.org/en/stable/tutorials/scripting/gdextension/gdextension_cpp_example.html
I have installed my "gcc" and g++ with Cygwin

after running these commands
mkdir gdextension_cpp_example
cd gdextension_cpp_example
git init
git submodule add -b 4.2 https://github.com/godotengine/godot-cpp
cd godot-cpp
git submodule update --init
I have godot-cpp folder in my project and the command
godot --dump-extension-api
produced extension_api.json
and finally, I am running the Scons
scons platform=windows custom_api_file="D:\godotNET\gdextension_cpp_example\extension_api.json"
its producing output
scons: Reading SConscript files ...
scons: warning: No version of Visual Studio compiler found - C/C++ compilers most likely not set correctly

and finally its showing

scons: *** [bin\libgodot-cpp.windows.template_debug.x86_64.a] The system cannot find the file specified
scons: building terminated because of errors.
not sure what i am missing is it the documentation wrong or something with the scons build file?
Note: I am not using any Visual Studio or VS code
Steps to reproduce
mkdir gdextension_cpp_example
cd gdextension_cpp_example
git init
git submodule add -b 4.2 https://github.com/godotengine/godot-cpp
cd godot-cpp
git submodule update --init
godot --dump-extension-api
scons platform=windows custom_api_file="

we can follow the same thinghttps://docs.godotengine.org/en/stable/tutorials/scripting/gdextension/gdextension_cpp_example.html
even though the object files are getting created in the scr/classes folder, but the "libgodot-cpp.windows.template_debug.x86_64.a" is not getting created

I have tried a couple times now and have not been able to reproduce this.
scons v4.6, minggw v12.2, windows 10
Are you sure that it's using gcc/g++?
If you have MSVC installed, and don't pass the use_mingw=yes argument to scons, then it'll use MSVC.
Can you try adding that argument? Or, you could add verbose=yes, and it'll print out the command it's running, which should make it clear which compiler it's using.
I was also trying to install, and this particular file took me like 15 minutes (I thought it was an error, so I found this GitHub issue). By the way I also passed bits=64 to the command, I don't know if that was helpful.
