Sorry about this.
Opencv is divided into some libraries.
These libraries are divided for every function.
However, the pkg-config file of opencv has a form depending on all the
libraries,
and developer and user may demand a library without necessity.
Therefore, Debian, package is divided for every library and the dependency
of a library is held according to the dependency of package.
Although this is already reported to upstream with the patch, it does
not apply yet[0].
It is necessary to put libopencv-dev into build dependency to use
opencv by pkg-config.
Moreover, each library can be specified when not using pkg-config.
Although I had described this information to README.Debian, since
information was old, I updated.
