I have got installed pkg-conf and pkgconf (which is said to be the newer=
=20
one). I can deinstall pkg-conf but the results are the same. cmake=20
reports it is calling pkgconf and not pkg-conf when checking for lv2.

I can't deinstall pkgconf because it is needed by jackd2, ...

The command "ls /usr/include/lv2" reports all the directories are there.
