[Kde-imaging] How to test KIPI plugins?

[Martin Engelmann]

Hello,

I would like to modify one of the KIPI plugins, but I don't know how to
test the modification. I have installed 0.4.0 via the package management
and I would like to keep that. But for testing purposes I would like to
switch to the modified version.
I experimented with LD_LIBRARY_PATH but was not successful.

Is there an howto or some other documentation out there?

Thank you very much!

Martin
