hello, when i build slicer, i enter \<ccmake -DCMAKE\_BUILD\_TYPE:STRING=Release DQt5\_DIR:PATH=/home/zbs/package/Qt/5.12.2/gcc\_64/lib/cmake/Qt5/Qt5Config.cmake …/Slicer\>  
i meet errors as follows, maybe the reason is i install qt more than one.Could you give me some advice? Thank you very much.

Considering setting `Qt5_DIR` to `/home/zbs/package/Qt/5.12.2/gcc_64/lib/cmake/Qt5` instead of `/home/zbs/package/Qt/5.12.2/gcc_64/lib/cmake/Qt5/Qt5Config.cmake`

Hi Jean,

I have tried with “cmake -DCMAKE\_BUILD\_TYPE:STRING=Debug -DQt5\_DIR:PATH=/usr/lib/x86\_64-linux-gnu/cmake/Qt5/ …/…/Slicer” , but still i’m getting same errors.

In your last attempt to configure, you used `/usr/lib/x86_64-linux-gnu/cmake/Qt5/` instead of `/home/zbs/package/Qt/5.12.2/gcc_64/lib/cmake/Qt5`

I suggest the following:  
(1) Use the version of Qt5 installed in `/home/zbs/package/Qt/5.12.2/`  
(2) Make sure that WebEngine and QtScript are installed. The files `Qt5Script/Qt5ScriptConfig.cmake` and `Qt5WebEngine/Qt5WebEngineConfig.cmake` should exist in the directory `/home/zbs/package/Qt/5.12.2/gcc_64/lib/cmake`. If not, update your Qt install to install the corresponding components. See [https://www.slicer.org/wiki/Documentation/Nightly/Developers/Build\_Instructions#Linux](https://www.slicer.org/wiki/Documentation/Nightly/Developers/Build_Instructions#Linux)

```auto

```
