Need help with custom moc commands.

[Michaël Larouche]

(Please CC to me as I am not a member of kde-buildsystem)

In Kopete (kdenetwork/kopete/protocols/jabber/libiris to be more precise), I 
have some files where both header and implementation has the Q_OBJECT.

The Makefile.am used this trick:

s5b.lo: s5b.moc

CLEANFILES = s5b.moc
s5b.moc: $(srcdir)/s5b.cpp $(srcdir)/s5b.h
	${MOC} $(srcdir)/s5b.h > $@
	${MOC} $(srcdir)/s5b.cpp >> $@

and here my attempt to reproduce it in CMake:

# BEGIN moc special case
# Those are special cases, both header and implementation contains a Q_OBJECT 
macro
# What we do is generate a moc file for both header and implementation and 
with CMake FILE command, create the final .moc
qt4_generate_moc( ${CMAKE_CURRENT_SOURCE_DIR}/iris/xmpp-core/securestream.h 
${CMAKE_CURRENT_BINARY_DIR}/securestream_h.moc )
qt4_generate_moc( ${CMAKE_CURRENT_SOURCE_DIR}/iris/xmpp-core/securestream.cpp 
${CMAKE_CURRENT_BINARY_DIR}/securestream_cpp.moc )
qt4_generate_moc( ${CMAKE_CURRENT_SOURCE_DIR}/iris/jabber/s5b.cpp 
${CMAKE_CURRENT_BINARY_DIR}/s5b_cpp.moc )
qt4_generate_moc( ${CMAKE_CURRENT_SOURCE_DIR}/iris/jabber/s5b.h 
${CMAKE_CURRENT_BINARY_DIR}/s5b_h.moc )

set(securestream_h_MOC)
set(securestream_cpp_MOC)
set(s5b_h_MOC)
set(s5b_cpp_MOC)

# Create securestream.moc
file(READ ${CMAKE_CURRENT_BINARY_DIR}/securestream_h.moc securestream_h_MOC)
file(WRITE ${CMAKE_CURRENT_BINARY_DIR}/securestream.moc ${securestream_h_MOC})
file(READ ${CMAKE_CURRENT_BINARY_DIR}/securestream_cpp.moc 
securestream_cpp_MOC)
file(APPEND ${CMAKE_CURRENT_BINARY_DIR}/securestream.moc 
${securestream_cpp_MOC})

# Create s5b.moc
file(READ ${CMAKE_CURRENT_BINARY_DIR}/s5b_h.moc s5b_h_MOC)
file(WRITE ${CMAKE_CURRENT_BINARY_DIR}/s5b.moc ${s5b_h_MOC})
file(READ ${CMAKE_CURRENT_BINARY_DIR}/s5b_cpp.moc s5b_cpp_MOC)
file(APPEND ${CMAKE_CURRENT_BINARY_DIR}/s5b.moc ${s5b_cpp_MOC})

# END moc special case

The resulting MOC with CMake doesn't compile, and I need a cleaner way to do 
it.

Thank you
