function compile
%COMPILE compile JIGSAW's c++ backend using cmake.
%
%   COMPILE tries to compile JIGSAW from the c++ source code
%   available in ../external/jigsaw. The cmake utility and a
%   c++ compiler must be available on the system path.
%
%   On success, JIGSAW is installed in ../external/jigsaw.
%
%   The cmake workflow has been tested on various Linux, Mac
%   and Windows-based systems, using the gcc, clang and msvc
%   compilers.
