title: TYPO3 8.7 TCA ext_tables.php check
body: <p>I've started a new project with <code>TYPO3 CMS 8.7 LTS</code> and I've created my own distribution- (or provider-) extension for <code>TypoScript</code>, <code>TSconfig</code> and HTML-Templates -- like usual.</p>
  
  <p>At the new <code>Install Tool</code> there's a check: <strong>TCA in ext_tables.php check</strong></p>
  
  <pre><code>Extensions change TCA in ext_tables.php
  Check for ExtensionManagementUtility and $GLOBALS["TCA"].
  </code></pre>
  
  <p>I've read, that the <code>ext_tables.php</code> should be (nearly) empty. So my file only contains the link to my static typoscript file:</p>
  
  <pre><code>&lt;?php
  if (!defined('TYPO3_MODE')) {
      die ('Access denied.');
  }
  
  \TYPO3\CMS\Core\Utility\ExtensionManagementUtility::addStaticFile($_EXTKEY, 'Configuration/TypoScript', 'Distribution Extension');
  </code></pre>
  
  <p>That's all. But why is the Install-Tool-Check not successful?</p>
  
  <p>I've also <a href="http://www.typo3forum.net/discussion/79689/typo3-cms-8-7-1-fehler-bei-den-modulen-protokoll-und-erweiterungen" rel="nofollow noreferrer">read</a>, that this command should be in <code>typo3conf/ext/distribution_ext/Configuration/TCA/Overrides/sys_template.php</code>, but If I try, I can't choose my distribution in backend (root template -> include static template) ..?</p>
  
  <p>What is the perfect way to include static template files in TYPO3 8.7?</p>
