Well, after some wrangling, I've managed to get CTags indexing at least 
partially working. I'd still like to have full cross-referencing 
ability, but we'll take what we can get for now.

Depending on the make output to do this seems really naive to me, but 
even after modifying the build to echo its compile commands, I'm still 
not having much luck.

One thing that might be nice would some way to have an external script 
generate the data the indexer needs. This could be configured as a 
builder and it could deal with the complexities of the given build tree.

The current approach just doesn't cut it for real projects.
