Subject: Fix an issue when building in directories that are symlinks.
X-Git-Url: http://sigrok.org/gitweb/?p=libsigrok.git;a=commitdiff_plain;h=3535a6eeee267ebb0092a0f6600b0b3edc055bf8

Fix an issue when building in directories that are symlinks.

Explicitly use SRCDIR and BUILDDIR in Doxyfile files to reference input
files. This seems to be a sufficient fix for an issue where the build
would fail when libsigrok/ was located in a directory that was a symlink.

This fixes bug #547.
