@jorgeneo560 You need to update your submodule

Hi,

I think I have the same issue but building from a docker.

Error:

CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
_MAVLINK_INCLUDE_DIR

I let you know if I found the issue

[Jaeyoung-Lim]

@Katawann I don't think your issue is related. The builds are checked in the CI, so I suspect there is something wrong specific to your setup.

Why not use the setup script (Tools/setup/ubuntu.sh) to install the dependencies?

[Katawann]

Indeed... I succeed to do it with an updated dockerfile. Sorry for bringing up the subject again
