# This makefile provides recipes to build a "portable" version of scrcpy for
# Windows.
#
# Here, "portable" means that the client and server binaries are expected to be
# anywhere, but in the same directory, instead of well-defined separate
# locations (e.g. /usr/bin/scrcpy and /usr/share/scrcpy/scrcpy-server).
#
# In particular, this implies to change the location from where the client push
# the server to the device.
