[poky] Building sysroot for SDK

[Patrick]

Dear list,

I use poky 6.0 to build a complete rootfs for my own target, it's working nicely !Now I would like to build a small application SDK for my system. 

I have red carefully the ADT manual and decided to build a toolchain with meta-toolchain. The toolchain generated works properly but some libraries and headers are missing. 
For example my target use SQLite built in the rootfs. The sqlite library and the headers files are missing in the toolchain.

I would like to know how to build the sysroot to add those files in the toolchain or how to add it directly to the toolchain.

Thanks in advance for any help

Patrick
