## Bash script for setting up a PX4 development environment for Pixhawk/NuttX targets in Bash on Windows.
## It can be used for installing the NuttX toolchain (only).
##
## Installs:
## - Common dependencies and tools for all targets (including: Ninja build system, pyulog)
## - FastRTPS and FastCDR
## - NuttX toolchain (i.e. 64 bit version of gcc compiler)
## - PX4/Firmware source (to ~/src/Firmware/)
