Hello all,
I maybe have a spare solution for you , until MbedStudio team not finish it in the future.
Currently I have 4 projects with one separete Mbed OS linked by simple command MKlink.
mklink /d “C:\Users\USERNAME\Mbed Programs\mbed-os-empty\mbed-os” “C:\Users\USERNAME\MbedLib\mbed-os”
If you are interested, check the sources.
It looks functional but I do not know what will happened when new version of MbedOS will come.
BR, Jan
