<p>The Meson feature for Eclipse is an optional feature of the CDT (C/C++ Development Tools) that adds support for maintaining and
building C/C++ projects that use the Meson build system. The Meson build system is akin to Autotools in that a project is configured before building. Like Autotools, configuration involves testing the build system and toolsets supported. Once configured, the project is built by a second tool, akin to the Make tool used in Autotools. While Meson supports more than one Make-like tool to build the project, the CDT Meson plug-ins currently only have support for "ninja".</p>
<p>The configuration data for the project is stored in a file called: "meson.build". This file contains directives that are interpreted by the <b>meson</b> command. Directives include which languages are used, what executables/targets are created, sources, special configuration options, and any special build-time tests among other things. Many tests are automatic so the configuration file does not require much.</p>
<p>The following is a sample <i>meson.build</i> file:</p>
<p><code>
project('hello', 'c')
<br/>
executable('hello', 'hello.c')
</code>
</p>
<p>This file tells <i>meson</i> that the project name hello is a C project and that it creates a single executable called <i>hello</i> which is formed from <i>hello.c</i>. Meson will find the C compiler, etc.. needed to build this project on this build machine.</p>
<p>Running meson in the directory containing <i>meson.build</i> will create a <i>ninja.build</i> file in the <b>build</b> directory (or specified build directory).</p>
