I assume you are getting this error when configuring your project with a
copy of VTK's CMake-ified freetype, but not when configuring VTK itself.
The error message you are getting tells you to set
CMAKE_BACKWARDS_COMPATABILITY to 1.4.  Did you try this?

The VTK freetype CMake code was never designed to be built stand-alone
outside VTK.  What you can do is include this in your project:

INCLUDE(${CMAKE_ROOT}/Modules/CMakeBackwardCompatibilityC.cmake)

You can also probably use the CHECK_TYPE_SIZE macro to set
CMAKE_SIZEOF_INT yourself.
