How to develop

Hi kate devs,

I'm trying to build `kate` locally and install it into my private prefix
`~/.kate.dev`. I want to ensure that all plugins used also from the prefix
instead of system-wide installed `kate` from the package. What I see in the
`strace` output it still use the system-wide plugins instead of locally
built.

Could you please give me some advise how to enforce locally installed
plugins to be used. I've tried `LD_LIBRARY_PATH` but it doesn't help at
all... according to strace the `~/.kate.dev/bin/kate` even doesn't lookup
this dir for plugins %(

Thx
