Hi Bill,

thanks for replying... yes, you guessed it pretty much:

INCLUDE_DIRECTORIES(
"${CMAKE_SOURCE_DIR}/scribus"
)
SET(COLORWHEEL_PLUGIN_MOC_CLASSES
colorblind.h
colorwheel.h
colorwheelwidget.h
cwdialog.h
cwsetcolor.h
)

SET(COLORWHEEL_PLUGIN_SOURCES
colorblind.cpp
colorwheel.cpp
colorwheelwidget.cpp
cwdialog.cpp
cwsetcolor.cpp
)

SET(SCRIBUS_COLORWHEEL_PLUGIN "colorwheel")
IF(QT_WRAP_CPP)
  SCRIBUS_QT_WRAP_CPP(${SCRIBUS_COLORWHEEL_PLUGIN} 
${COLORWHEEL_PLUGIN_MOC_CLASSES})
ENDIF(QT_WRAP_CPP)

ADD_LIBRARY(${SCRIBUS_COLORWHEEL_PLUGIN} MODULE ${COLORWHEEL_PLUGIN_SOURCES} 
${COLORWHEEL_PLUGIN_MOC_SOURCES})


So theres not much different.. apart from the moc setup which all seems to 
work fine (as it does in the main code). Perhaps the only surprise there is 
the SCRIBUS_QT_WRAP which gives me class.moc instead of moc_class.cxx files. 
This is the first plugin I've attempted to get working from all you will see 
in the plugins directory (aside from some STATIC ones not in this directory 
which work fine).
