Expected behavior

Not error

Actual behavior

*WARNING: if the actual behaviour suggests memory corruption (like a crash or an error
from a memory checker), then the bug should be assumed to have security
implications (until proven otherwise), and we ask what you report it privately,
see the note at the top of this template.

• with cmake

I'm following GitHub and https://mbed-tls.readthedocs.io/en/latest/getting_started/ documentation
with git submodule update --init --recursive it works

git submodule update --init --recursive

mkdir build
cd build
cmake ..
