# building qgroundcontrol for raspberry pi 4
# steps:
#   1. compile QT for raspberry Pi:
#       - the version of QT that comes with debian doesn't compile
#         QGC correctly, so we compile a newer version
#       - this can take up to 8 hours even with 4 cores
#   2. compile qtlocation
#   3. compile qgroundcontrol using qt5.12.8

# this assumes a desktop environment is present to actually run qgc once it's compiled
