Creates a new set of build configurations for all targets in the project.
The number and names of the build configurations is a project-wide setting. Each target has the same number of build configurations and the names of these build configurations is the same. The created configurations are initially empty. Care must be taken to fill them with reasonable defaults. The function throws an exception if a build configuration with the given name already exists.
