[Bug] Errors compiling v1.15 and main on Ubuntu 20.04

[gsoga]

Describe the bug

Ubuntu 20.04
PX4 versions tested: 1.14, 1.15, main
Platform: px4_fmu-v6x

Results:

• v1.14 with make px4_fmu-v6x_default: compiles ok

• v1.15 and main with make px4_fmu-v6x_default: error related with septentrio

  PX4-Autopilot/src/drivers/gnss/septentrio/sbf/messages.h:101:10: error: 'septentrio::sbf::Header::id_number' is too small to hold all values of 'enum class septentrio::sbf::BlockID' [-Werror]
  101 | BlockID id_number: 13;

• I am interested in trying the new rover implementation and I have tested make px4_fmu-v6x_rover with v1.15 and with main and I got an additional error:

  PX4-Autopilot/src/modules/ekf2/EKF/ekf.h:56:10: fatal error: ekf_derivation/generated/state.h: No such file or directory
  56 | #include <ekf_derivation/generated/state.h>

  I checked the directory and it was generated. Again I tried make px4_fmu-v6x_rover and got the first error:

  PX4-Autopilot/src/drivers/gnss/septentrio/sbf/messages.h:101:10: error: 'septentrio::sbf::Header::id_number' is too small to hold all values of 'enum class septentrio::sbf::BlockID' [-Werror]
  101 | BlockID id_number: 13;

I see that the error related with septentrio has been mentioned in:
