Trouble Building Qt4 Plugin - moc not being invoked?

[Lindsay Mathieson]

Searching on google seems to indicate an issue with moc not being invoked. 
Have been banging my head aginst this for days now.

Trying to build a shared plugin for QtWebKit, which uses the Qt4 plugin 
systems but can't get past the following link errors:

Linking CXX shared library lib/libkdewebkit-spellplugin.so
CMakeFiles/kdewebkit-spellplugin.dir/kspellplugin.o: In function 
`KWebKitSpellChecker':
/data/dev/kdewebkit-spellplugin/kspellplugin.h:19: undefined reference to 
`vtable for KWebKitSpellChecker'
CMakeFiles/kdewebkit-spellplugin.dir/kspellplugin.o: In function 
`TestQWebKitPlatformPlugin':
/data/dev/kdewebkit-spellplugin/kspellplugin.h:47: undefined reference to 
`vtable for TestQWebKitPlatformPlugin'
collect2: ld returned 1 exit status
make[2]: *** [lib/libkdewebkit-spellplugin.so] Error 1
make[1]: *** [CMakeFiles/kdewebkit-spellplugin.dir/all] Error 2
make: *** [all] Error 2
*** Failed ***


My cmake file is pretty basic:

project(kdewebkit-spellplugin)

find_package(KDE4 REQUIRED)
FIND_PACKAGE(Qt4 REQUIRED)

include (KDE4Defaults)

include_directories(/data/dev/webkit-blackpaws-kde-qt-
webkit/Source/WebKit/qt/Api)
include_directories( ${KDE4_INCLUDES} ${QT_INCLUDES} )


ADD_LIBRARY(kdewebkit-spellplugin SHARED kspellplugin.cpp kspellplugin.h)

target_link_libraries(kdewebkit-spellplugin ${KDE4_KDEUI_LIBS} 
${QT_LIBRARIES})



Part of the header if relevant:

class KWebKitSpellChecker : public QWebSpellChecker {
  Q_OBJECT
public:
    Sonnet::Speller *m_speller;
    
    KWebKitSpellChecker() 
	{
		m_speller = new Sonnet::Speller();
	}
    ~KWebKitSpellChecker() 
	{
		delete m_speller;
	}
