| <p>This module is able to find a version of DCMTK that does or does not export |
| a <em>DCMTKConfig.cmake</em> file. It applies a two step process:</p> |
| <ul class="simple"> |
| <li>Step 1: Attempt to find DCMTK version providing a <em>DCMTKConfig.cmake</em> file.</li> |
| <li>Step 2: If step 1 failed, rely on <em>FindDCMTK.cmake</em> to set <cite>DCMTK_*</cite> variables details below.</li> |
