# 2. Git Repositories
# pip wheel handles git urls perfectly
pip wheel --wheel-dir=./wheels \

# 3. Extensions with Custom Build Steps (nvdiffrast, diffoctreerast, mip-splatting)
# These often require cloning first if they have submodules or complex setups

# nvdiffrast
mkdir -p /tmp/extensions
if [ ! -d "/tmp/extensions/nvdiffrast" ]; then
    git clone https://github.com/NVlabs/nvdiffrast.git /tmp/extensions/nvdiffrast
fi
pip wheel --wheel-dir=./wheels /tmp/extensions/nvdiffrast

# diffoctreerast
if [ ! -d "/tmp/extensions/diffoctreerast" ]; then
    git clone --recurse-submodules https://github.com/JeffreyXiang/diffoctreerast.git /tmp/extensions/diffoctreerast
fi
pip wheel --wheel-dir=./wheels /tmp/extensions/diffoctreerast

# mip-splatting (diff-gaussian-rasterization)
if [ ! -d "/tmp/extensions/mip-splatting" ]; then
    git clone https://github.com/autonomousvision/mip-splatting.git /tmp/extensions/mip-splatting
fi
pip wheel --wheel-dir=./wheels /tmp/extensions/mip-splatting/submodules/diff-gaussian-rasterization/

# 4. Pre-built Wheels (Kaolin, torch-scatter, spconv)
# These are already wheels, so we just download them to the folder
pip download --dest ./wheels \
    kaolin==0.16.0 -f https://nvidia-kaolin.s3.us-east-2.amazonaws.com/torch-2.5.0_cu124.html

pip download --dest ./wheels \

# 5. Python-PyCG
pip wheel --wheel-dir=./wheels 'python-pycg[all]'
