The&nbsp;cmake build scripts are single threaded, but the compilation of the source files is not. Ten minutes is quite long. My desktop setup isn&#39;t particularly powerful, but I&#39;m on Linux, which helps, and building the&nbsp;matter light bulb&nbsp;took 2 minutes and 10 seconds on&nbsp;my system.&nbsp;</p> <p>Could you describe your setup? Could it be a problem with the antivirus?&nbsp;</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
