Hi,
from team of vcpkg I requested to add mbed-os as package ready to instal and include in project.
Here is github issue: [New Port Request] <mbed-os> · Issue #9421 · microsoft/vcpkg · GitHub
My knovledge for now s not enough to close PR by myself yet.
But if someone have enough resources can speedup development of package
vcpkg is good and reliable tool, that can speed up development
Best regards
Adam
