<p>On Linux you can also get a JDK from the Linux distribution. On apt-based distros (like Debian and Ubuntu), <code>sudo apt-get install openjdk-<VERSION>-jdk</code> is typically enough to install a JDK <VERSION>.

<p>If a required library is not detected by <code>configure</code>, you need to provide the path to it. There are two forms of the <code>configure</code> arguments to point to an external library: <code>--with-<LIB>=<path></code> or <code>--with-<LIB>-include=<path to include> --with-<LIB>-lib=<path to lib></code>. The first variant is more concise, but require the include files an library files to reside in a default hierarchy under this directory. In most cases, it works fine.</p>

This directory typically looks like <code>build/linux-x64-normal-server-release</code>, but the actual name depends on your specific configuration. (It can also be set directly, see <ahref="#using-multiple-configurations">Using Multiple Configurations</a>). This directory is referred to as <code>$BUILD</code> in this documentation.</p>

If you have all prerequisites for building installed, it should find everything. If it fails to detect any component automatically, it will exit and inform you about the problem.</p>
