For the latest documentation on Visual Studio 2017, see Project Build Error PRJ0032 on docs.microsoft.com. The 'Outputs' property for the project-level custom build step contained 'macro' which evaluates out to 'macro_expansion'.
A custom build step on a project had bad output probably due to a macro evaluation problem. This error could also mean that the path is badly formed, containing characters or combinations of characters that are illegal in a file path.
To resolve this error, fix the macro or fix the path specification. The evaluated path is an absolute path from the project directory.
