Dear Huier,<br>ITK and Qt are two independent libraries and work independently. Your problem is not related to Qt.<br><br>It seems a project configuration error, related to the CMakeLists.txt. Make sure in your project's CMake you are linking it (TARGET_LINK_LIBRARIES) to the ITK_LIBRARIES.<br>
<br>Anyway, when compiling ITK, if you are compiling it as shared library, a single dll is produced, ITKCommon.dll <br>Make sure you have the environment variable ITK_DIR pointing to the folder where you have your ITKConfig.cmake, and make sure your program is using this and not other versions.<br>
Make sure you are providing CMake with the corresponding ITK_DIR path (same as above).<br>Make sure you have compiled ITK for each configuration (debug, release, etc.) you want to build your project for.<br><br>If you are not using CMake to configure your project, using it will be of help in order to avoid these kind of errors.<br>
<br>You will proably find other related posts that may help you through the process.<br><br>Kind regards,<br>JON HAITZ<br><br><br>
