[CMake] How to write CMakeLists.txt for Qt4 when Q_OBJECT in xxx.cpp file

[1+1=2]

Thanks for your advice. I just want the project to be able to work
under both cmake and qmake.

I found an answer, which seems to work now.


PROJECT(mytest)
CMAKE_MINIMUM_REQUIRED(VERSION 2.6)
FIND_PACKAGE(Qt4 COMPONENTS QtCore QtGui REQUIRED)
INCLUDE(${QT_USE_FILE})
SET(pro_SOURCES  main.cpp)

QT4_GENERATE_MOC(main.cpp main.moc)
SET_SOURCE_FILES_PROPERTIES(main.cpp PROPERTIES OBJECT_DEPENDS main.moc)

INCLUDE_DIRECTORIES(${CMAKE_CURRENT_BINARY_DIR})
ADD_DEFINITIONS(${QT_DEFINITIONS})
ADD_EXECUTABLE(mytest  ${pro_SOURCES})
TARGET_LINK_LIBRARIES(mytest ${QT_LIBRARIES})
