        <pre>I've finished a experimental prototyping.

There are several commits of refrigerating CMake scripts. This is the
important part:

<span class="quote">&gt; <a href="https://github.com/fujii/webkit/commit/fffdb707fe123742a5440d5ec4a9c074f1c82d7c">https://github.com/fujii/webkit/commit/fffdb707fe123742a5440d5ec4a9c074f1c82d7c</a></span >

I've got well understanding thought this experiment.

<span class="quote">&gt; C) Implement Make-like tool in Python or Perl</span >

This approach is better than others because more precise dependency
updating checking is possible.  For example, my patches solve the
problem updating supplemental_dependency.tmp triggers regenerating all
bindings.

And, Perl is better than Python because generate-bindings.pl is
written in Perl.  If generate-bindings.pl will be converted to Perl
Module, I can stop using fork&amp;exec for speed and avoiding Windows
quoting command problem.

Ninja deletes all output files before executing a command.
So, I need to use add_custom_target.

Can I proceed?</pre>
