Its probably because the pam-face-authentication package contains
FindOpenCV.cmake which is compatible with only 2.1.0 and lower in
extracteddir/cmake/modules/ you can delete that, remove the build directory
and try again. It should work. let us know if it works.

It worked, but now I get a bunch of error messages when compiling
qt-facetrainer.
You'll find them attached.
Thanks

mmm... it seems it's actually installed. Did APIs change between 2.1.0 and
2.2.0?

exaclty the same problem/errors on my archlinux.

APIs changes between 2.1.0 and 2.2.0 are massive. see:

OpenCV API changes might be massive, but I was able to compile the today's svn
revision (340) with OpenCV 2.2.9 without any problems.
At first, I replaced the trunk/qtbranch/cmake/modules/FindOpenCV.cmake with
OpenCVConfig.cmake from my OpenCV build folder, because the provided
FindOpenCV.cmake was not working.
Then I needed to change two lines in the trunk/qtbranch/CMakeLists.txt, so that
it used OpenCV_LIBS variable instead of OPENCV_LIBRARIES (diff attached)
and after that, the compilation was successful.

I would suggest this thread can be change to "Can't build with opencv >=2.2.0."
Yes, there is OpenCV 2.3. And there is no update, even latest svn does not
build.

Hi, I tried out the suggestion in #7.
It builds & works for openCV 2.3.0.

Update: I've tried to investigate and fix this issue. Sadly I can't come up
with a solution because it's weird somehow.
OpenCV 2.3 has it's own OpenCVConfig.cmake which replaces FindOpenCV.cmake (as
correctly stated above). Nevertheless we have to keep backward compatibility
with lower version, so the question is how to integrate a universal(!)
FindOpenCV.cmake AND support the old way.
I got some infos from http://opencv.willowgarage.com/wiki/FindOpenCV.cmake
but what was bothering me is the fact that the old OpenCV 2.1 had all header
includes in /usr/include/opencv, OpenCV 2.3 suddenly expected them to be in
/usr/include/opencv2.
In OpenCV 2.3 the variable OpenCV_LIBRARIES isn't used any longer, right now
it's named OpenCV_LIBS. Sadly I can't simply change it for backward
compatibility reasons.
You see...awkward situation :-/
Any help is greatly appreciated!

I know it sounds dirty.
But I used the patched CMakeList.txt and the FindOpenCV.cmake from OpenCV 2.2 .
They work both in OpenCV 2.2&2.3.
May someone try with earlier version?

That's a perfectly valid way of solving this issue. Nevertheless
FindOpenCV.cmake might be different on every system, so sadly we can't just
integrate it. And of course there's still the compatibility issue.
IMHO the most appropriate way of dealing with this is a generalized
FindOpenCV.cmake which handles OpenCV 2.2 & 2.3 as well as the old 2.1 (or
lower).

I couldn't help but consider this kind of backward compatibility could not be
always worthy, especially as the time flies by.
More & more user are likely switched to newer version of OpenCV by now even
without their attention.
And also, I think OpenCV 2.1 couldn't be built with libpng 1.5 by now, which
suggests it might be deprecated enough.
So please allow me to ask boldly: would you please move on to support newer
version of OpenCV?
Personally, I'm not good at CMake, and trying to find the old remedy
FindOpenCV.cmake which worked for me by now.

For ubuntu 12.04:
cd /tmp && wget

tar.gz
tar zxf pam-face-authentication-0.3.tar.gz && cd pam-face-authentication-*
cp /usr/share/OpenCV/OpenCVConfig.cmake ./cmake/modules/FindOpenCV.cmake
nano /cmake/modules/FindOpenCV.cmake
--SET(OpenCV_INCLUDE_DIRS "${OpenCV_INSTALL_PATH}/include/opencv;${OpenCV_INSTALL_PATH}/include")
++SET(OpenCV_INCLUDE_DIRS "/usr/include/opencv;/usr/include")

mkdir build && cd build
cmake -D CMAKE_INSTALL_PREFIX=/usr ..
make
sudo checkinstall --pkgname=pam-authentication-face-auth
It work!

Thank you for providing this patch.
I was able to build current SVN with the fixed root CMakeLists.txt.
But 2 faulty link.txt generated:
./CMakeFiles/qt-facetrainer.dir/link.txt
./CMakeFiles/pam_face_authentication.dir/link.txt
These files wouldn't be able to link the object file properly.
I have to manually add my OpenCV related so file to the -rdynamic arguments.
I will try your new FindOpenCV soon.
Could you merge your patch into official branch? That would be great help for
some other distros as well.
Thank you again.

The .deb on post #17 work fine in Linux mint 17 (cinnamon edition) later the
installation i only have to create symbolic link of opencv library, this
because qt-facetrainer looks for version 2.3 and in mint 17 are installed
opencv version 2.4, later symbolic link added all works fine
