Thanks! :)

With this variant, I see in the build output that DX_INCLUDE is set:

SRCDIR='.' PROJECT='opensaml' DOCDIR='doc/api' VERSION='2.6.0'
PERL_PATH='/usr/bin/perl' HAVE_DOT='YES' DOT_PATH='/usr/bin'
GENERATE_MAN='NO' GENERATE_RTF='NO' GENERATE_XML='NO'
GENERATE_HTMLHELP='NO' GENERATE_CHI='NO' GENERATE_HTML='YES'
GENERATE_LATEX='NO' DX_INCLUDE=/usr/include /usr/bin/doxygen ./doxygen.cfg

With this one, it seems DX_INCLUDE isn't set:

SRCDIR='.' PROJECT='opensaml' DOCDIR='doc/api' VERSION='2.6.0'
PERL_PATH='/usr/bin/perl' HAVE_DOT='YES' DOT_PATH='/usr/bin'
GENERATE_MAN='NO' GENERATE_RTF='NO' GENERATE_XML='NO'
GENERATE_HTMLHELP='NO' GENERATE_CHI='NO' GENERATE_HTML='YES'
GENERATE_LATEX='NO' DX_INCLUDE= /usr/bin/doxygen ./doxygen.cfg

and doxygen emits lots of warnings about undocumented stuff.

So I'll go with the manual expansion.
