Description
A recent change in opencv.pc replaces traditional -L/full/path/dir -ldep in Libs: pkg-config field by less traditional /full/path/dir/libdep.so
This raises an issue with libtool. libtool is not able to create a shared library and link it against other shared libraries specified with such a full path.
Eg. libtool --mode=link gcc -o libtarget.la libdep.lo /full/path/dir/libdep.so fails (the dependency libdep is ignored). This is a long standing issue in libtool.
This issue in libtool has never been fixed because the semantics of specifying such a full path for creating shared libraries is not well defined (according to libtool developers).
So I suggest fixing opencv.pc and revert it to what has always done for .pc files, e.g -L/dir -ldep, which is known to work everywhere.
Attached patch is a suggestion on how to implement this.
(BTW, installing 3rd party libraries in /shared is really a bad idea, since /shared is arch independent, but that's another issue :)

Thanks for your suggestion.
Actually the problem is deeper than choosing between full and relative paths. For now I'm closing this issue as a duplicate.
