Hi,

I have been trying to build the custom apps from the examples (Demo0, SimpleParaView) with no success.

My build procedure is as follows. x64 Native Tools Command Prompt for VS 2019:

1. cmake -S path\_to\_example\_source -B path\_to\_build\_dir -DParaView\_DIR=path\_to\_paraview\_build
2. cmake --build path\_to\_build\_dir --config Release

This all runs fine but when I run .exe, several files like pqComponents-pv5.10.dll, pqApplicatonComponents-pv5.10.dll, or pqCore-p5.10.dll are not found.

Can somebody point out what I am doing wrong?

Kind regards,  
Davis

You need to add paraview bin directory to your PATH env var.
