Require CMake 2.6.3 or higher

Previously we required CMake 2.6.1 or higher, but CMake 2.6.3 provides
component-wise VERSION_LESS, VERSION_GREATER, and VERSION_EQUAL tests in
the if() command and the CMAKE_VERSION variable.  Once the running CMake
is known to be 2.6.3 or higher, tests against its version are simple.

We also use the FATAL_ERROR option to CMAKE_MINIMUM_REQUIRED() to ensure
that CMake 2.4 gives up with an error immediately.
