[yocto] shared cmake modules

[Gabriele Zampieri]

Hi,

yes, following:

- cmake-modules.bb https://pastebin.com/5VqN9msS
- xxx-log.bb : https://pastebin.com/LYcPW3hc

The first one install the modules, thus is a dependency of many libraries,
the second one is a simple logger library that uses first's module

Thanks for your help,
Gabriele
