embedXcode release 22 includes two new targets: Make and Fast.
The Make and Fast targets feature an optimisation for the build of the foundation libraries, which include the core, application and user libraries.
The first time the Make and Fast targets are launched, they build all the foundation libraries into an archive for later reuse. Fast also uploads and opens a serial console.
The second launch of the Make and Fast targets are launched, they only compile the main sketch and the local libraries, and link them reusing the foundation archive built previously.
They are much faster than the corresponding Build and All targets. This is especially important for the ARM-based boards.
