From f04092c0b16dc11c1d871bf59a8fe94c10cdb6e3 Mon Sep 17 00:00:00 2001
From: Robin Gareus <robin@gareus.org>
Date: Mon, 30 Sep 2019 04:39:37 +0200
Subject: [PATCH] Update Doxygen config:

* process only header files (API is supposed to be documented there)
  (this resolves various inheritance and ambiguities, as well)
* Set pre-processor defines as a normal Ardour compile would
* Expand Macros (fixes issues with visibility defines)
