The shared-desktop-ontologies mess

[Alexander Neundorf]

Hi Sebastian,

kdebase here still doesn't build for me without SDO.
We have the following in kdelibs/CMakeLists.txt:

set(SOPRANO_MIN_VERSION "2.3.70")
find_package(Soprano  REQUIRED COMPONENTS  
                      PLUGIN_RAPTORPARSER PLUGIN_REDLANDBACKEND)
macro_log_feature(SOPRANO_FOUND "Soprano" ... FALSE ... )
macro_log_feature(SOPRANO_PLUGIN_RAPTORPARSER_FOUND ... FALSE ...)
macro_log_feature(SOPRANO_PLUGIN_REDLANDBACKEND_FOUND ... FALSE ...)

macro_optional_find_package(SharedDesktopOntologies)
macro_log_feature(SHAREDDESKTOPONTOLOGIES_FOUND ... FALSE ...)

...

if(Soprano_FOUND AND SHAREDDESKTOPONTOLOGIES_FOUND)
  set(HAVE_NEPOMUK true)
  add_subdirectory(nepomuk)
endif(Soprano_FOUND AND SHAREDDESKTOPONTOLOGIES_FOUND)


Which means that soprano and SDO are considered optional in kdelibs and 
nepomuk is only built of both are present.
But then in kdepim the installed nepomuk files are used, which then fails: 
http://my.cdash.org/viewBuildError.php?buildid=39649

So, am I right that both soprano and DSO should be marked as hard dependencies 
for kdelibs ?
Otherwise everything which wants to use nepomuk from kdelibs needs to check 
whether the installed kdelibs has nepomuk actually.

So, ok, with making it required ?
