Should we support building utilities without building player?

[Matěj Laitl]

Hi amarok-devel,
while trying to solve Gentoo bug 390831 [1] I've found that it is currently 
(master branch) impossible to build Amarok utilities (amarokcollectionscanner 
and amarok_afttagger) without building the player itself. (Gentoo allows it 
among all other combinations)

[1] https://bugs.gentoo.org/show_bug.cgi?id=390831

The build failure in the bug report can be easily solved by moving 
configure_file(config-amarok.h.cmake ...) in CMakeLists around, but then a more 
serious one appears:

shared/FileTypeResolver.cpp:57: undefined reference to `KMimeType::is(QString 
const&) const'

The problem is that we don't require (and link to) kdelibs in utilities-only 
build. Because using mime type when identifying files is useful and I've found 
no Qt KMimeType alternative, I think we have 2 options:

a) do not support building utilities without building player
b) require kdelibs in utilities-only build

I can do the b), but is there an actual use-case for building only utilities? 
Would linking to kdelibs hamper this use-case? (Paweł, Thomas?)
