[CMake] Handle lib64 library on Linux

[Sara Rolfe]

Hi Eric,

Thanks for your reply.  I tried setting the  
FIND_LIBRARY_USE_LIB64_PATHS property, but this did not resolve the  
problem.  I will read through the bug report you linked to.  Below is  
my CMakeLists.txt file.  Could you let me know if you see any issues?

Thanks,
Sara

cmake_minimum_required(VERSION 2.6)

PROJECT(Geo)

FIND_PACKAGE(ITK)
IF(ITK_FOUND)
	INCLUDE( ${USE_ITK_FILE} )
ENDIF(ITK_FOUND)

FIND_PACKAGE(VTK)
IF(VTK_FOUND)
INCLUDE( ${USE_VTK_FILE} )
ENDIF(VTK_FOUND)


ADD_EXECUTABLE(SubsampleVolume SubsampleVolume.cxx )

set_property(GLOBAL PROPERTY FIND_LIBRARY_USE_LIB64_PATHS ON)

TARGET_LINK_LIBRARIES(SubsampleVolume
	ITKNumerics ITKIO ITKBasicFilters vtkRendering vtkIO vtkWidgets 	 
vtkHybrid)
