Local workspace overlay

[marcoag]

Build a package in a local workspace which depends on packages supplied for the platform.

Run the tests for the package - all of them should pass.

For source platforms, this means building the candidate package in a separate workspace from the one used in the installation instructions.

TODO: Create a "dummy" package that ensures that we can target other packages using CMake, link against them, and run executables (tests) that are linked against libraries in the main workspace.

Configuration

• OS: Ubuntu Noble 24.04
• Chip set: AMD64
• Build type: Binary
• DDS: ConnextDDS
