描述

If you import a wrapped project with errors in its build definition will produce an error: Also couldn't find a fallback subproject in subprojects/<project_name> for the dependency <dep_name>

While the error could just be a wrong spelled source file in subprojects/<project_name>/*/meson.build. We expect it to say that the project has errors not that the project doesn't exist.

As sample: This project imports the subproject without error except that it doesn't build(not completed yet..). This project shows the error while I just added a wrong source file in the subproject build definition.

研究方向
Locate the error message in the source code, likely in the subproject handling module. The error message is generated when a project with errors is imported. Search for the string 'couldn't find a fallback subproject' in the codebase. Modify the logic to detect if the subproject exists but has errors, and provide a more specific error message. Check linked sample projects for reproduction.
