draco/CMakeLists.txt
Ondrej Stava dc28e6a2ea Updated Draco to 1.1.0 
The latest version of Draco brings a number of new compression
enhancements for even smaller models:
- Improved compression
  - Up to 40% better compression of normals
  - Up to 5% better compression for models with multiple attributes
- Faster decode speeds
  - 30% faster decoding for models with multiple attributes for lower compression levels 4 and below
    - Note: Decreases compression by 10%.
- Encoding of metadata to .obj (e.g. Draco can preserve material or sub-object names)
- Security fixes
