Automatic Project Configuration

Select any target as Build or Make, and click on Run.

The utility starts and prepares the project.

Updated Parameters

The .pde or .ino files are declared as C++ code for code-sense.

The directories for the targets are set to allow the click-to-error.

All the cores, variants and libraries of the installed platforms are under the new Resources group.

Additionally, the makefiles are declared with the type makefile.

Finally, all the sources for code-sense are declared.

When removing files from the Resources group, always select Remove References and not Move to Trash.
