The problem is that automoc seems to strip "/usr/include". If I manually add
something like "/usr/include/banana" it shows up, but /usr/include not.

I need /usr/include as phonon is located there (/usr/include/phonon/*.h)

Ok, so here we have the case that another library installs header, which are accessed via the system include search path, which is then stripped from the include dirs for a target. This one here is even independent from messing with CMAKE_CXX_IMPLICIT_INCLUDE_DIRECTORIES as in the phonon case, since /usr/include is part of the default CMAKE_CXX_IMPLICIT_INCLUDE_DIRS as set in Modules/Platforms/UnixPaths.cmake.

So I guess instead of simply querying the target for its include directories, automoc needs to query the target for its include dirs without having the system include dirs stripped away.

This should now really be fixed in the TheRealAutomocIncludeDirFix branch on cmake stage.
Can you give this a try ?

Thanks, both phonon and phonon-vlc build correctly with the patch from that branch.

Merged into next, this will be in the next release.
