Hi @fluber, I’m not quite sure, what the point of your question is? Anyway, the default way would be to - Use the latest verion of the CMake GUI - Configure for VS 2015 x64 - Generate - to get the VS solution - Open solution in VS 🙂 As the _CMakeLists.txt_ shows, you will need to have a local copy of Qt 5.12. Also an environment variable **CMAKE\_PREFIX\_PATH** , pointing to the location of your Qt, is required. ---

Hi @fluber, The standard builder for Visual Studio Projects with CMake should really be _“Visual Studio 14 2015”_ (or, if you have installed the 64 bit version of Common Vision Blox, _“Visual Studio 14 2015 Win64”_). ---

> [@rtp\_derahs](#): > > VS 2015 x64 Mind the exact name of the builder. It is **“Visual Studio 14 2015 Win64”**. According to the cmake documentation, x64 will be rejected on the command line. ---

Hi @fluber, since a few days we can also offer you an online help on how to build the applications: [Getting Started with CVB Tutorials](https://help.commonvisionblox.com/NextGen/14.0/md_theory_of_operation_appnotes__c_v_b_tutorials.html). ---

the QtStatisticsDisplay example is ok. the QmlCookieClassification example is failed. I don’t know this. cmake log. **setting up CVB Qt bridge for UI components - do not forget to link CVB::CvbUI** How do I fix it. ---

Good morning @fluber, the message _setting up CVB Qt bridge for UI components - do not forget to link CVB::CvbUI_ is only a warning, not an error. Simply continue, the example will work nonetheless. But thank you for the information, I will put this into the Getting Started guide. 👍 ---

the QtStatisticsDisplay example is ok. I can successfully build the project and run. but the QmlCookieClassification example is failed. ![A](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/1X/fbf380885a4c952397a603606ebacfd4fee0ec90.png) ![B](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/1X/170a3dbddace8f2181787ca48dbe6e625315beb3.png) ![C](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/1X/0b1f192f22d955a7486d9dc8a9528eecbfd851f1.png) ![D](https://canada1.discourse-cdn.com/flex027/uploads/commonvisionblox/original/1X/5a84c611954e292a884e0869eb1752cf3b27be02.png) ---

I remove the “Common Vision Blox Bindings 1.00.000 (x64)” and reinstall “CommonVisionBlox 13.02.000 (x64)”. the do “cmake generate…” again. then I can successfully build the project. “QmlCookieClassification” ---
