[2023.2] CONFIG_FILE and CONFIG_TMPL variables in makefile of examples

[brucebenedictus]

Hi,

I want to run the the HLS examples in the 2023.2 branch. The makefile in the examples use the environment variable CONFIG_FILE and CONFIG_TMPL.
My infrastructure uses these environment variables already.

Would it be possible not to check if the variables are already set?

just to append to the issue of Bruce

The issue here is that gitlab-ci is using the CONFIG_FILE variable too.
https://docs.gitlab.com/runner/commands/#configuration-file
And probably many others.

Putting a kind of namespacing to the global Vitis variables (e.g. 'xlnx_' or 'vitis_') could solve this.
