[PD] compiling pix_opencv on debian (lmde)

[Benjamin ~ 01xy]

Hello pd-list,

I'm trying to compile pix_opencv on linux mint debian
when :
./configure --with-pd=path_to_pd --with-gem=path_to_gem
I get :
checking for cvSobel in -lcv... no
configure: error: you need to install opencv library (libcv)

of course, I've previously installed libcv2.3 libcv-dev libcvaux-dev 
libhighgui-dev with the package manager
locate libcv gives :
...
/usr/lib/libcv.so.4
/usr/lib/vlc/plugins/codec/libcvdsub_plugin.so
/usr/share/doc/libcv-dev
/usr/share/doc/libcv2.3
/usr/share/doc/libcvaux-dev
/usr/share/doc/libcvaux2.3
/usr/share/doc/libcv-dev/README.Debian
...

did anyone already managed to compile pix_opencv on debian testing ?
any magic ln -s command ? maybe pix_opencv relies on opencv v1 ?

thanks
benjamin
