Help using newest OPC UA Modules/IOCs

["Marco A. Barra Montevechi Filho via Tech-talk" <tech-talk at aps.anl.gov>]

Hi, all.

We are finally taking some time to update our OPC UA IOCs here at Sirius. Im using the main Ralph Lange's repository to build the modules:

https://github.com/epics-modules/opcua/tree/v0.9.4

And also the Assets distributed: 

https://github.com/epics-modules/opcua/releases/tag/v0.9.4

Particularly the one for debian 11: https://github.com/epics-modules/opcua/releases/download/v0.9.4/IOC_opcua-0.9.4_Base-3.15.9_debian11.tar.gz

However, as someone who is not a PLC or OPC UA expert, i fail to understand the difference between the whole repository and only the asset.
Extracting the tar file from the provided asset, pointing to EPICS_BASE path in its configure/RELEASE file and building works just fine.

Cloning the whole repository, pointing to EPICS_BASE and GTEST in its configure/RELEASE file doesnt work. The build fails with the compilation message that i append below.

My main question is: can i simply use the asset instead of the whole module in the repository? If yes, what will i be missing?
Also, in my GTEST build, i didnt write any particular test because i dont know how to use this module. Is it necessary?

Thanks for your time,

Marco
