Summary:                    Too many include paths are set to AM_MOC_INCLUDES in
AutomocInfo.cmake then the build fails.
Description: 
  I want to use following classes in ITK and ParaView for image conversion
between ITK and Qt through VTK.

itk::ImageToVTKImageFilter< TInputImage >
http://www.itk.org/Doxygen/html/classitk_1_1ImageToVTKImageFilter.html

itk::VTKImageToImageFilter< TOutputImage > 
http://www.itk.org/Doxygen/html/classitk_1_1VTKImageToImageFilter.html

http://www.paraview.org/ParaView/Doc/Nightly/www/cxx-doc/classpqCoreUtilities.html

  So, I wrote a CmakeLists.txt as below and generated a solution for Visual
Studio 11(MSVC 2012) Win64 with Cmake GUI successfully, but subsequent build
process with MSVC fails every time.

  I found out that the build stop is caused from moc failure via too many
include paths set to AM_MOC_INCLUDES in the file “(build
directory)/CmakeFiles/(project name)_automoc.dir/AutomocInfo.cmake”.

  I can finish build process by deleting some paths in AM_MOC_INCLUDES, but I
think it's very hard task and there is no guarantee for right build in this way.

  I know that it might not be a bug in Cmake, and be a limitation of moc. But
it's a critical limitation in the development together with ITK, VTK, ParaView,
and Qt.

  So, I appreciate if you show a solution or some workarounds for this problem.
Thank you in advance.

Steps to Reproduce: 
  Generate a solution for MSVC 2012 Win64 with following CmakeLists.txt, then
build it by Visual Studio.


CmakeLists.txt:

cmake_minimum_required(VERSION 2.8.11 FATAL_ERROR)
if(POLICY CMP0020)
  cmake_policy(SET CMP0020 NEW)
endif()
project(MocTest.1.0)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
set(CMAKE_AUTOMOC ON)
find_package(Qt5Widgets REQUIRED)
find_package(ITK REQUIRED NO_MODULE)
include(${ITK_USE_FILE})
FIND_PACKAGE(ParaView REQUIRED)
INCLUDE(${PARAVIEW_USE_FILE})
file(GLOB CXX_FILES *.cxx)
file(GLOB CPP_FILES *.cpp)
add_executable( MocTest.1.0 ${CXX_FILES} ${CPP_FILES} )
target_link_libraries( MocTest.1.0
  Qt5::Widgets ${ITK_LIBRARIES} ${PARAVIEW_LIBRARIES}
)

Additional Information: 
List of softwares, libraries:

Microsoft Visual Studio Express 2013 for Windows Desktop
  (Solution generated with CMake is for MSVC 2012)
  Solution Platform: x64
