I remade the dbus-qt3 package which changed the default install location to:

/usr/include/dbus-1.0/dbus/connection.h
/usr/include/dbus-1.0/dbus/dbus-qt.h
/usr/include/dbus-1.0/dbus/message.h
/usr/include/dbus-1.0/dbus/server.h
/usr/lib/libdbus-qt-1.a
/usr/lib/libdbus-qt-1.so
/usr/lib/libdbus-qt-1.so.1
/usr/lib/libdbus-qt-1.so.1.0.0

I've picked through the ConfigureChecks.cmake to look at what is actually failing.

   check_cxx_source_compiles("
     #include <dbus/connection.h>
     int main(int, char**) { return 0; } "
     HAVE_DBUS_QT3_07 )

 From http://www.cmake.org/Wiki/CMake:How_To_Write_Platform_Checks I see:

Module
     INCLUDE (CheckCXXSourceCompiles)
     INCLUDE (CheckCSourceCompiles)
Usage
     CHECK_CXX_SOURCE_COMPILES(source variable)
     CHECK_C_SOURCE_COMPILES(source variable)

Checks whether the code given in source will compile and link. You can set 
CMAKE_REQUIRED_LIBRARIES, CMAKE_REQUIRED_FLAGS and CMAKE_REQUIRED_INCLUDES 
accordingly if additional libraries or compiler flags are required.

OK - it looks like check_cxx_source_compiles is looking for the 'source':

"   #include <dbus/connection.h>
     int main(int, char**) { return 0; } "

to then set the 'variable':

     HAVE_DBUS_QT3_07

which isn't getting set and causing the cmake configure failure.

Looking at the #include <dbus/connection.h>, I added:

/usr/include/dbus-1.0 to CMAKE_INCLUDE_PATH

and kdebase now configures and is starting it's build. We will see how far we 
get this time :)
