Sanitizing the contents of the QTPLUGIN variable, and adding default plugins from the available modules, should be a separate step before the resulting QTPLUGIN is iterated and processed by for example linking to each plugin, generating an import file, and adding module dependencies. This makes it easier to add logic to the processing step later on. Change-Id: I00e826c7fe87b29cf2e6bf4e1901c4d1482a20e6 Reviewed-by: Alexandru Croitor <alexandru.croitor@qt.io>
