I2CDev / MPU6050 libs incompatibility build error fix

[pppedrillo]

The I2CDev and MPU6050 libraries used in the project are not compatible with the latest PlatformIO lib registry and thus cause build error (see attached screenshot) with the latest PlatformIO core v5.2.4 /expressif8266 platform v3.2.0

The examples of failure :

https://github.com/universam1/iSpindel/runs/4759700794?check_suite_focus=true

These changes include both 2 libs as a part of the project (as advised on PIO and by libs author https://github.com/jrowberg/i2cdevlib ) and thus fix the building error.

How on earth does an update in PlatformIO lead to the need for 26 file changes! What did the PlatformIO guys do!?

It is not "26 files changes" , but rather "1 file changed + 25 files added"

Briefly :
Up to PlatformIO 3 (2.6.3 the latest) all the platform libs (including those 25 files) are getting downloaded automatically during the build. You can see em all in your .pio/libdeps/<your_target> folder.
Since PlatformIO 3 PIO handles a registry of verified packages and I2Cdev libs is not adapted for being included into this registry, thus are not downloaded during the build (only their .piopm and json get downloaded, but not the sources) - thus no headers and build failed.

If you really interested in this, you can find all the info in PIO docs.

It is mostly I2Cdev lib developer's fault - he has not changed his lib to be compatible with the PIO registry. If you check i2CDev repo, you'll see it was last time updated 2-3 years ago. PIO encouraged all the shareholders to make changes for upcoming migration in 2019-2020.

As a result if you still have PIO 2.6.3 (or older) installed - your build will be fine.
If you have latest 3.2.0 (like for instance github autobuild use) - your build will fail.

These changes make build work fine with any of PIO installed.

@pppedrillo thanks for the info. Quite interesting. Nice job figuring out what needed to get sorted. Well done.
