- cmake NuttX build wrapper compile in place instead of copying source tree to build directory
- slightly faster skipping necessary copying (depending on system)
- allows debugging in place
- easier to work directly in NuttX following official documentation
- simplifies overall build which should make it easier to resolve any remaining NuttX dependency issues in the build system
- the downside is switching back and forth between different builds always require rebuilding NuttX, but I think this is worth the improved developer experience
- also no longer builds px4io and bootloader in every single build, for most users these rarely change and we're wasting a lot of build time
There is a platform, NixOS Linux, on which '/bin/bash' is not available.
This commit changes the interpreter to '/usr/bin/env bash' in some
scripts essential to firmware building.
Ubuntu 20.04 and latest Cygwin come with no Python 2 and no link
from python to python3. To not mess with the system we detect
python3 for seamless support.
