Error when building with different package structure

[ahi-bplus]

When building a package with a project structure like camera_calibration from the ros image_pipeline, I get the ModuleNotFoundError.

structure with ModuleNotFoundError:

package_name/
├── src
│   └── package_name
│       ├── __init__.py
│       ├── node.py
│       ├── parameters.yaml
│   ...

When teh package is structure like

package_name/
├── package_name
│       ├── __init__.py
│       ├── node.py
│       ├── parameters.yaml
│   ...

everything works.

The problem lies in the hard-coded install_dir/build_dir, e.g.:

generate_parameter_library/generate_parameter_library_py/generate_parameter_library_py/setup_helper.py

Line 64 in 268d5e4

build_dir = os.path.join(colcon_ws, 'build', pkg_name, pkg_name)

How could we solve the problem?
