Compile GafferCycles with OIDN

Trying to compile the [https://github.com/boberfly/GafferCycles/tree/oidn](oidn branch of gafferCycles) to get OpenImageDenoise working in Gaffer.

# Compile with vfx reference platform docker
docker run -it --mount type=bind,source=/pod/sw/compile/gaffercycles,target=/root --mount type=bind,source=/opt,target=/root/opt --entrypoint /bin/bash gaffercycles-1

# Set up env
export GAFFER_ROOT=~/opt/gaffer/gaffer
# export GAFFERCYCLES=~/opt/gaffer/extensions/gafferCycles-oidn-0.10.2-gaffer-0.54.2.0
export GAFFERCYCLES=/root/gafferCycles-oidn-0.10.2-gaffer-0.54.2.0
export LD_LIBRARY_PATH=$GAFFER_ROOT/lib
export PATH=$GAFFER_ROOT/bin:$PATH
export PYTHONHOME=~/opt/gaffer/gaffer
export GITHUB_RELEASE_TOKEN=10.2

git clone --recurse-submodules https://github.com/boberfly/GafferCycles.git

cd GafferCycles

# modify dependencies/build/build.py to bypass ssl checking so gflags compiles
import ssl
ctx = ssl.create_default_context()
ctx.check_hostname = False
ctx.verify_mode = ssl.CERT_NONE
urllib.urlretrieve( download, archivePath, context=ctx)

scl enable devtoolset-6 bash

Compile as Debug instead of Release

Compile with vfx reference platform docker

docker run -it --mount type=bind,source=/pod/sw/compile/gaffercycles,target=/root --mount type=bind,source=/opt,target=/root/opt --entrypoint /bin/bash gaffercycles-1
