CMake macros should use installed paths instead of relative build/source paths

[xmfcx]

Description

The three exported CMake macros use hardcoded relative paths from CMAKE_BINARY_DIR and CMAKE_SOURCE_DIR to locate scripts and resources:

Macro	Relative paths used
autoware_system_designer_build_deploy.cmake	${CMAKE_BINARY_DIR}/../autoware_system_designer/script/deployment_process.py, system_designer_runner.py, resource/; ${CMAKE_SOURCE_DIR}/../autoware_system_designer as PYTHONPATH
autoware_system_designer_generate_launcher.cmake	${CMAKE_BINARY_DIR}/../autoware_system_designer/script/generate_node_launcher.py, system_designer_runner.py
autoware_system_designer_parameter.cmake	${CMAKE_BINARY_DIR}/../autoware_system_designer/script/parameter_process.py, system_designer_runner.py

This assumes the autoware_system_designer source and build trees coexist as siblings of the consuming package at build time. This breaks when:

• Staged Docker builds clean build artifacts between stages (e.g., via build_and_clean.sh), so the build directory no longer exists when a downstream package tries to use the macro
• The package is pre-installed (e.g., from a debian/apt package)
• Someone builds with --packages-select <consumer> without autoware_system_designer in the same workspace

Suggested fix

Install the scripts to the package's share directory, then derive the path in the -extras.cmake from the installed find_package result. For example:

# In CMakeLists.txt - install scripts
install(DIRECTORY script/ DESTINATION share/${PROJECT_NAME}/script)

# In the exported cmake macros
set(SYSTEM_DESIGNER_RUNNER_SCRIPT "${autoware_system_designer_DIR}/../../share/autoware_system_designer/script/system_designer_runner.py")

This works from both the colcon workspace build and the install space.

🎗️ In summary, the constraint is that Package A is not allowed to require the build folder of the dependency Package B.

Context

• Encountered while adding autoware_system_designer to the Autoware Docker build
• feat(repositories/autoware.repos): add autoware_system_designer v0.3.1 and fix Docker rosdep autoware#7000
• CI failure: https://github.com/autowarefoundation/autoware/actions/runs/24246105106/job/70792727232?pr=7000

[xmfcx]

• Until this issue is resolved, we'll have to revert revert(autoware_sample_designs): revert autoware system designer systems (#1751) autoware_launch#1814 because autoware_core CI is blocked otherwise.

@xmfcx
Thank you for your work.

I fixed the root cause by #48. Please confirm the issue is resolved.

I created a new version of the system designer, and update PR autowarefoundation/autoware#7010
