As an update, it turns out the the odd file (call this this fileZ in question
is compiled into a 'moc' file by the qt moc compiler and has the extension
.moc. The starting file is a .cpp file which does not seem to need to use
of QT4_WRAP_CPP()? (though I am not expert enough to be sure).
I thus tried an add_custom_command() (gleaned from moc --help)) that looks
like the following:-
configure_file(PATH/to/fileZ.cpp PATH/to/fileZ2.h @COPYONLY)
set(MOC_cmd "/opt/qt4/bin/moc")
set(PRePRCESSOR_STIRNG "xxxx yyy zzz")
ADD_CUSTOM_COMMAND(
OUTPUT -o ${CMAKE_BINARY_DIR}/path/to/fileZ.moc
COMMAND ${MOC_cmd}
-I${QT_INCLUDES}
-I${CMAKE_SOURCE_DIR}/path/to
-E${PRePRCESSOR_STIRNG}
${CMAKE_BINARY_DIR}/path/to/fileZ2.h
DEPENDS ${CMAKE_SOURCE_DIR}/path/to/fileZ.cpp )
but (apart from the first line) it did not work.
advice would be appreiated.
