We will now deal with the application that loads these plugins:

1. Create a new Subproject inside ch08-image-animation
2. Select the Qt Widgets Application type
3. Name it image-animation and accept the default Class Information settings

We have a few last things to do in the .pro files. First, image-animation will try to load the plugins from somewhere in its output directory. Because each filter-plugin project is independent, its output directory is separated from image-animation. Thus, each time you modify a plugin, you will have to copy the compiled shared library inside the proper image-animation directory. This works to make it available to the image-animation application, but we are lazy developers, right?

We can automate this by updating plugins-common-pri, like so:

INCLUDEPATH += $$PWD/sdk 
DEPENDPATH += $$PWD/sdk
