Module setup steps gives missing file error

[CadeEvs]

Setting up the module lists these steps

git clone https://github.com/ocornut/imgui
git -C imgui checkout v1.91.6-docking
git clone https://github.com/godotengine/godot
cd godot
scons custom_modules=../modules
cd ../project
godotenv addons install
../godot/bin/godot.* -e

Following these steps exactly gives this error when running the scons command

fatal error C1083: Cannot open include file: 'imconfig-godot.h': No such file or directory
