Mbed CLI 2 not linking BlueNrg HCI drivers

[boraozgen]

Description of defect

When building the examples with Mbed CLI 2 for DISCO_L562QE, I noticed that the BlueNrg HCI drivers do not get linked, resulting in a Please provide an implementation for the HCI driver error on initialization.

I then noticed that mbed-ble-blue_nrg CMake library does not get linked anywhere. I added this to the main CMake file:

target_link_libraries(${APP_TARGET} PRIVATE mbed-ble-blue_nrg)

and it started working. Of course this should be done in the Mbed CMake files according to the target configuration.

Otherwise CLI 2 builds for NRF52_DK without issues (had some problems with path lengths but it is Windows specific).

Target(s) affected by this defect ?

DISCO_L562QE

Toolchain(s) (name and version) displaying this defect ?

GCC for arm-none-eabi 9.3.1

What version of Mbed-os are you using (tag or sha) ?

mbed-os-6.9.0

What version(s) of tools are you using. List all that apply (E.g. mbed-cli)

mbed-tools 7.5.0

How is this defect reproduced ?

Try building + running an example for DISCO_L562QE with Mbed CLI 2.

The issue isn't that it doesn't build. It builds without issues, albeit without linking the HCI driver, which gives an error in runtime:

Please provide an implementation for the HCI driver

You can also search for the mbed-ble-blue_nrg CMake target and see that it is not linked anywhere.
