Summary0007102: QT4_GENERATE_MOC doesn't generate any rules
DescriptionTest project:

foo.cpp:
#include <QObject>
#include "foo.moc"

class Foo: public QObject
{
        Q_OBJECT
};

CMakeLists.txt:
cmake_minimum_required(VERSION 2.6)
FIND_PACKAGE(Qt4 REQUIRED)
INCLUDE_DIRECTORIES( ${CMAKE_CURRENT_BINARY_DIR}
                     ${QT_INCLUDES} )
QT4_GENERATE_MOC(${CMAKE_CURRENT_SOURCE_DIR}/foo.cpp foo.moc)
ADD_EXECUTABLE( foo foo.cpp )
TARGET_LINK_LIBRARIES( foo ${QT_LIBRARIES} )

Make complains about foo.moc not found. That's correct, foo.moc generating rule wasn't added.

The rule is not generated because the generated foo.moc is not used anywhere (from the cmake POV).
Add foo.moc to the list of source files (and use the full path):

SET(FOO_MOC_FILE "${CMAKE_CURRENT_BINARY_DIR}/foo.moc")
....

ADD_EXECUTABLE( foo foo.cpp ${FOO_MOC_FILE})

This should make it work.
If it doesn't, please reopen the bug report.
