Build GDCM from source and it will have the necessary finders. Do not
INSTALL. Then the usual in your CMakeLists.txt file. Here is an
example.

CMakeLists.txt
cmake_minimum_required(VERSION 2.6)
	
	PROJECT(GDCMImageViewer)
	
	FIND_PACKAGE(VTK REQUIRED)
	INCLUDE(${VTK_USE_FILE})
	
	FIND_PACKAGE(GDCM REQUIRED)
	INCLUDE(${GDCM_USE_FILE})
	
	INCLUDE_DIRECTORIES(
	 ${GDCM_SOURCE_DIR}/Utilities/VTK
	)
	
	IF(WIN32 AND NOT CYGWIN)
	        ADD_SUBDIRECTORY(getopt)
	        INCLUDE_DIRECTORIES(getopt)
	ENDIF(WIN32 AND NOT CYGWIN)
	
	ADD_EXECUTABLE(GDCMImageViewer gdcmviewer.cxx)
	TARGET_LINK_LIBRARIES(GDCMImageViewer vtkHybrid vtkInfovis vtkWidgets
vtkgdcm getopt)
