[oe] Extending meta-toolchain-*

[Björn Krombholz]

Hi,

I need someone to point me in the right direction.

I'm trying to extend meta-toolchain-qte to generate an external 
toolchain for QTembedded with QWT.

What are the required steps to add any libraries/headers to toolchains?

I tried adding libqwt-dev to the RDEPENDS of the meta package itself or 
the affected task-qte-toolchain-target.bb.

This triggers a build of qwt when bitbaking meta-toolchain-qte, but the 
resulting toolchain tarball doesn't contain anything qwt related.

Any hints?


Thx
Björn
