I’m trying to execute ParaView custome apps but I have problems.

I generate with `cmake` without problem

But when I do `make` and `make install` I get and error because it seems to be looking for a file and file is not there

What do I need to do to execute these examples?

The only `paraview_clone1.app` that I have is in

`/Users/username/Desktop/dev/qt-examples/1/build/bin`

It looks like you’re trying to install into `/usr/local`. You need `sudo make install` to have enough permissions to install to that directory.
