■I was trying to build ParaView on Ubuntsu 18.04, foloowing
[https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md](https://gitlab.kitware.com/paraview/paraview/blob/master/Documentation/dev/build.md)
■And when I executed the following,
cmake -GNinja -DPARAVIEW\_USE\_PYTHON=ON -DPARAVIEW\_USE\_MPI=ON -DVTK\_SMP\_IMPLEMENTATION\_TYPE=TBB -DCMAKE\_BUILD\_TYPE=Release …/paraview
■I get warnings and errors like
CMake Warning at VTK/CMake/vtkModule.cmake:4222 (find\_package):
Could not find a configuration file for package “Qt5” that is compatible
with requested version “5.12”.
The following configuration files were considered but not accepted:
```
/usr/lib/x86_64-linux-gnu/cmake/Qt5/Qt5Config.cmake, version: 5.9.5
```
Call Stack (most recent call first):
Qt/Core/CMakeLists.txt:166 (vtk\_module\_find\_package)
CMake Error at VTK/CMake/vtkModule.cmake:4228 (message):
Could not find the Qt5 external dependency.
Call Stack (most recent call first):
Qt/Core/CMakeLists.txt:166 (vtk\_module\_find\_package)
– Configuring incomplete, errors occurred!
See also “/home/kazuya/paraview\_build/CMakeFiles/CMakeOutput.log”.
See also “/home/kazuya/paraview\_build/CMakeFiles/CMakeError.log”.
■As the warning says, I thought that this is due to Qt version, so installed Qt 5.12. And this is apparently okay as below.
kazuya@en005031:~/Qt5.12.0/5.12.0/gcc\_64/lib$ qmake --version
QMake version 3.1
Using Qt version 5.12.0 in /home/kazuya/Qt5.12.0/5.12.0/gcc\_64/lib
■I’ve got no idea how to solve this, so I’d be really grateful someone could help me.
Thanks in advance. Kazuya.

Clearly, you should configure CMake to find Qt 5.12 instead of 5.9.5

Thank you for your response. Could you specifically tell me how I can do this?

First clean your build dir, then, something like:
`cmake -DQt5_DIR=~/Qt5.12.0/5.12.0/lib/cmake/Qt5 ../paraview`

■Now, the error regarding Qt has hopefully gone, but the next step ninja doesn’t work. In /paraview\_build/bin, I only find
paraview.conf
paraview-config
After cmake, there were some suspicious “Failed”, “not found” as below, which might be related?

If you want to use ninja, you should configure for it.
First clean your build dir, then, something like:
`cmake -GNinja -DQt5_DIR=~/Qt5.12.0/5.12.0/lib/cmake/Qt5 ../paraview`

Now I have successfully completed build and was able to run ParaView.
Thank you very much for your kind help!
