Enable selective compilation of Arduino libraries. Makes a big difference for projects which use entire Arduino library for late linking purposes (as in COMPONENT_ADD_LDFLAGS := -Wl,--whole-archive -l$(COMPONENT_NAME) -larduino-esp32 -Wl,--no-whole-archive)

I incorporated Your comments and use this updated version in my code successfully. So the answer is Yes :)

I have some build error since this update.
I have added some libraries on my libraries folder and I have these warning :

/home/Jyce/esp/arduino/components/arduino/component.mk:3: avertissement : variable « CONFIG_ARDUINO_SELECTIVE_ESPAsyncWebServer » indéfinie
/home/Jyce/esp/arduino/components/arduino/component.mk:3: avertissement : variable « CONFIG_ARDUINO_SELECTIVE_AsyncTCP » indéfinie

Adjust Kconfig.projbuild accordingly to support the new libraries You added locally.

If I unset selective compilation, it should scan and build all lib in the folder.

Indeed, You have a point there. What would You believe is the right behaviour if You choose selective compilation and pick some, what should happen with Your added libraries? Should they go in or out? Or a checkbox like "include additional"?

By the way, I still hope there is way to trick IDF to regenerate Kconfig... You just got me a bit closer to researching that.

Good question. "include additionnal" will help users that do not know how to add them manually. It could be a good idea.

If I don't get a bright idea how to adjust Kconfig automatically, that seems the next best solution. @me-no-dev - any ideas/comments from You?

Here is how it should work. If a library is not in the list for selection, it should be automatically included, regardless of what is selected in the menu.
