KDevelop syntax parser is barely usable

Just some related feedback,

I work with the Audacity source code (0.6k lines of code
Kdevelop 5.2.4, Ubuntu 16.04.

Kdevelop rarely crashes for me, so the database does not need to reparse
from scratch very often, but I still often see KDevelop reparsing very
slowly due to code changes outside of KDevelop (such as when Git bisecting).

I have also been struggling with the problems of KDevelop not seeing
macros, templates, not finding definitions, not finding declarations ... In
short, parsing only works for about 50% of the Audacity code, whereas
KDevelop 3 gave about 90% coverage. The problem may be in part, due to
Audacity now making more use of C++11, and a little C++14, with more
templates and broader use of "modern" C++ idioms. Regardless of the
reasons, the problem for me remains that KDevelop 5 syntax parser does not
work at all well for Audacity source code.

The case for Audacity is complicated due to it using WxWidgets and
automake, but KDevelop 3 could mostly handle that reasonably well with a
bit of effort setting it up. I've been struggling with KDevelop 5 since it
was first released, and have managed to get it from "unusable" to "just
about usable".
