[vtkusers] Simple type that pulls in libvtkexpat

[Clinton Stimpson]

How about something like this:


In the C++ source code:
#include "vtkToolkits.h"

#ifdef VTK_USE_SYSTEM_EXPAT
...
#else
...
#endif



in a cmake file:

find_package(VTK)
include(${VTK_USE_FILE})
...
target_link_libraries(myapp ${VTK_EXPAT_LIBRARIES})
