Requires updates of expat and tiff submodules.
Most libraries have their own CMakeLists, add a comment with a suggestion to
use this for implementing build-in support.
Add the hardware-specific source files to the build systems. Do not add MIPS
and PowerPC to MSVC build files, because these include <stdint.h> which is not
available for old MSVC versions.
Add CMake build system for libraries, tests and samples
update_files.py converts build/files into CMake format.
build/update-setup-h has been modified to update build/cmake/setup.h.in.
