[CMake] CMake and Qt3

[Filipe Sousa]

FIND_PACKAGE(Qt)

ADD_DEFINITIONS(${QT_DEFINITIONS})
INCLUDE_DIRECTORIES(${QT_INCLUDE_DIR} ${CMAKE_CURRENT_BINARY_DIR})

QT_WRAP_CPP(qtwrapping moc_sources essai.h)
QT_WRAP_UI(qtwrapping headers sources essai.ui)
ADD_EXECUTABLE(qtwrapping main.cpp ${moc_sources} ${headers} ${sources})
TARGET_LINK_LIBRARIRES(qtwrapping ${QT_LIBRARIES})

That should do it
