# Pythonのインストール例
# /Applications/Xcode.app/Contents/Developer/Library/Frameworks/Python3.framework/Versions/3.9/Python3 を使ってもいいのかもしれない
pyenv install 3.9.16
pyenv local 3.9.16

# venvを使ってpipでパッケージをインストールする
python -m venv env
source env/bin/activate
python -m pip install --upgrade pip
python -m pip install pyside6 PyOpenGL	  

# USDはv23.02のソースコードを使う
git clone https://github.com/PixarAnimationStudios/USD PixarUSD
git switch -c v23.02

# PYTHONPATHが未定義の場合、build_usd.pyでのビルドに失敗するので宣言する
export PYTHONPATH=path/to/your/python

# ビルド
mkdir buildspace  
python PixarUSD/build_scripts/build_usd.py ./buildspace
