Unfortunately it's deeper than opencv itself.
Look at
/usr/ports/pobj/OpenCV-2.2.0/build-amd64/modules/highgui/CMakeFiles/opencv_highgui.dir/CXX.includecache:
---8<---
/usr/local/include/libxml2/libxml/xmlstring.h
stdarg.h
-
libxml/xmlversion.h
-
/usr/local/include/libxml2/libxml/xmlversion.h
libxml/xmlexports.h
-
ansidecl.h
-
---8<---
It comes from libxml.
Sadly, CMake is broken in this regard: if it sees this reference
and ansidecl.h is present, it will add a dependency upon it, even
if HAVE_ANSIDECL_H is never set.
The patch below should fix the problem (and I've applied the same
treatment to textproc/libxslt too, just to be sure).
I've googled the internet for other solutions, but found nothing.
Comments? OKs?
(CCing ports@ to wide the audience)
Cheers,
David
