Requested 'libusbmuxd >= 1.1.0' but version of libusbmuxd is 1.0.10

Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.

Alternatively, you may set the environment variables libusbmuxd_CFLAGS
and libusbmuxd_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
