- Install a library for SHA, e.g. sudo apt-get install libgcrypt11-dev (if not already present)
  - Otherwise the driver may throw an error with "_mesa_sha1_compute" when loading SPIR-V shaders

# Building
- Clone Mesa Master : git clone git://anongit.freedesktop.org/mesa/mesa -b Master
- cd mesa
- autoreconf -vfi
- ./configure --with-dri-drivers=i965 --with-gallium-drivers= --with-sha1= --with-vulkan-drivers=intel
