This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
This overload accepts a null-terminated string instead of requiring a

the real process output.
This class provides a RunProcess method to run a child process and send
its output to an abstract parsing interface. This also provides a
simple line parser and logger implementing the parsing interface.
