Cannot build openssl with dockcross Android-arm64 on Apple Silicon Mac

[rayw-dronesense]

Environment

• Apple M2 Max Macbook Pro

• 64 GB RAM

• Mac OS Ventura

• Docker Desktop 4.28.0

Problem

When trying to build MAVSDK repo on the main branch, and tried to run the configuration step following the documentation to use dockcross.

However, it fails every single time when it tries to build OpenSSL,

-- Configuring incomplete, errors occurred!

The command being used to configure the build is

~/dockcross-android-arm64 cmake -DCMAKE_BUILD_TYPE=Debug -Bbuild/default -DBUILD_MAVSDK_SERVER=ON -DBUILD_SHARED_LIBS=ON -H.

Would you be able to help? Thanks!

As of today (android-arm64:20240418-88c04a4 and MAVSDK tag v2.10.2) the command

~/dockcross-android-arm64 cmake -DCMAKE_BUILD_TYPE=Debug -Bbuild/default -DBUILD_MAVSDK_SERVER=ON -DBUILD_SHARED_LIBS=ON -H.
