Hello,

I installed VTK 7.1.1 on two systems (raspberry pi os and ubuntu 16). On the first system (raspberry pi os) everything works fine and my project builds in qt with cmake. Now I want to move the project to another computer and tried building it, but I get the following error:

```auto

15:53:22: The process "/usr/bin/cmake" exited normally.

Error while building/deploying project PCLViewer (kit: Desktop)

When executing step "Make"

```

I installed VTK like this:  
Terminal: wget [https://www.vtk.org/files/release/7.1/VTK-7.1.1.tar.gz](https://www.vtk.org/files/release/7.1/VTK-7.1.1.tar.gz)  
•Extract the folder in Downloads  
•Terminal: cd VTK-7.1.1  
•Terminal: mkdir build  
•Terminal: cd build  
•Terminal: cmake …  
•Terminal: make  
•Terminal: sudo make install

The system on which it is running has QVTKWidget.h under /usr/include/vtk-7.1, but on the other system this file seems to be missing after the installation.

I am assuming that this is the reason for the error. Any help would be appreciated.

Thanks!

Daniel

What options did you pass to `cmake` to build VTK? You at least need to enable the GUISupportQtOpenGL module (IIRC).
