#                    Add support for VAAPI. This is off by default but
#                    can be enabled by adding '--ignore-gpu-blacklist' and
#                    then one of '--use-gl=desktop' or '--use-gl=egl'.
#                    See https://chromium.googlesource.com/chromium/src/+/master/docs/gpu/vaapi.md#VaAPI-on-Linux
#                    for the intended usage (Intel VAAPI and MESA VAAPI).
#                    To support Nvidia and other GPUs, patches would be needed.

No values were supplied for the following variables:

You can supply your own Google API keys and compile them into Chromium now.
Else you can always provide Google API keys at runtime through the environment.
To achieve that, create '/etc/${PRGNAM}/01-apikeys.conf' as root:
  # echo "export GOOGLE_API_KEY='yourkey'" >> /etc/${PRGNAM}/01-apikeys.conf
  # echo "export GOOGLE_DEFAULT_CLIENT_ID='yourclientid'" >> /etc/${PRGNAM}/01-apikeys.conf
  # echo "export GOOGLE_DEFAULT_CLIENT_SECRET='yourclientsecret'" >> /etc/${PRGNAM}/01-apikeys.conf

Press Ctrl-C to abort this script and add your own Google API keys,
or wait 10 seconds to continue compilation without adding keys.
