[CMake] Double builds required in XCode w/CMake when changing UI code in QtDesigner

[Michael Jackson]

You might try the following:


add_executable ( Sumatra  ${SumatrSources} ${SumatraUISHeaders} )

and see what happens.


Here is a snippet from one of my own projects:


# -- Run MOC and UIC on the necessary files
QT4_ADD_RESOURCES( Generated_RC_SRCS ${ModelEditor_RCS} )

# this will run uic on .ui files:
QT4_WRAP_UI( Generated_UI_HDRS ${ModelEditor_UIS} )

# and finally this will run moc:
QT4_WRAP_CPP( Generated_MOC_SRCS ${ModelEditor_MOC_HDRS} )

#-- Put the generated files into their own group for IDEs
MXA_GENERATED_PROPERTIES(ModelEditor/Generated
                             "${Generated_UI_HDRS}"
                             "${Generated_MOC_SRCS}")

# -- Finally set the Project Sources to include all the sources
SET (${PROJECT_NAME}_PROJECT_SRCS
     ${ModelEditor_SRCS}
     ${ModelEditor_MOC_HDRS}
     ${Generated_RC_SRCS}
     ${Generated_UI_HDRS}
     ${Generated_MOC_SRCS}
)
ADD_EXECUTABLE( ${ModelEditor_EXE_NAME} ${GUI_TYPE} ${$ 
{PROJECT_NAME}_PROJECT_SRCS} )
