Need help with adding library dependeny

Hi there,

I've been working on a fix for
https://bugs.freedesktop.org/show_bug.cgi?id=44969 fdo#44969.

The fix replaces some XSLT constructs that aren't handled well
performance-wise by libxslt with exslt constructs.

We build and ship libexslt, but don't link against it when building
libxsltfilter, which breaks the build when building against our internal
copy of libxslt.

Unfortunately, I'm spoiled by Ant and suffer from severe Make dyslexia,
so I didn't manage to add that compiler and linker switches myself.

What should I do? I'd rather take a hint and fix it myself, but I could
also submit a patch to gerrit with a comment asking to fix the build
problem before pushing.

Thx a lot,

Peter
