How to build frei0r with mlt?

I'm currently trying to write a frei0r plugin that should remove stairsteps from d90 videos (see here).
After some fixes on frei0r itself I could even compile it. The patch (my plugin does not do anything yet) is here: d90patch.diff

The problem is now, when I build frei0r (with cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=debugfull) and make install it and then build and install mlt, there are no frei0r plugins in kdenlive.

I've installed frei0r-plugins-dev from the debian repo, but not frei0r-plugins.

frei0r and mlt from git, kdenlive from svn, all up-to-date.

What am I doing wrong?

Okay, one problem was that the libraries were installed to lib and not to lib/frei0r-1, as xzhayon pointed out.

I've got a fork here which I'm working on:

Not perfect, but working for now.
