[yocto] Merging a custom SDK with meta-toolchain-qt5

[Michel D'HOOGE]

Hi Karim, 

I understand your problem but unfortunately I still have a limited understanding of the intrication of the whole metadata system… 

The good news is that the meta-toolchain-qt5 recipe is quite empty. So I think your best option is to patch the populate_sdk task to include what is added by the qt5 layer. Once you have something working, you can then think on how to make it more permanent. 

grep & find will be your best friends --- at least, they are for me ;-)
