When you say "built against the Open Design Alliance Teiga library", what does that mean? Do they have their own dll that needs to be included, or do they have their own set of tools that need to be used to build gdal from source?</div>

It does. This is the first sentence: "OGR supports reading most versions of <br>
AutoCAD DWG when built with the Open Design Alliance Teiga library."<br>
Feel free to submit a PR to make it clearer (the doc of the DGNv8 driver<br>
<a href="https://gdal.org/drivers/vector/dgnv8.html">https://gdal.org/drivers/vector/dgnv8.html</a> is perhaps a bit clearer)<br>

The comment about building being ad-hoc is probably outdated. This is not so <br>
bad, at least on Linux<br>
<br>
>From what I've available there:<br>
<br>
For Linux<br>
./configure --with-teigha=/path/to/Teigha_lnxX64_5.3dll<br>
<br>
For Windows, you need to tweak with the TD_ variables in nmake.opt<br>
The instructions seems a bit outdated. I believe I tried on Windows, but don't <br>
have that config available anymore.<br>
