[HELP] how to make build use local espressif esp-hal-3rdparty dependencies?

[cederom]

Description

• I am working on a new board definition that has ESP32S3 chip.
• Experimenting requires frequent make clean distclean.
• On each iteration chip/esp-hal-3rdparty is fetched from scratch.
• This extremely slows down everything.
• @tmedicci @rcsim is it possible to pre-fetch all esp dependencies into a predefined location and make build use it from there instead fetching each time? :-)
• I could not find that in our docs. It this is possible and not yet in the docs I will update :-)
• Any hints welcome :-)

Verification

Hi @cederom -S adds the nxtmpdir folder for third-party packages.

is used on our CI in the build.yml workflow on GitHub

nuttx/.github/workflows/build.yml

Line 194 in 201406b

./cibuild.sh -c -A -N -R -S testlist/${{matrix.boards}}.dat

and if desired, you can use it locally
example

./tools/configure.sh -B -S esp32-devkitc:nsh

nuttx/tools/configure.sh

(-B selects the *BSD (B) host environment.) :)

At the moment, it is used only for
