configure: error: Package requirements (spice-protocol >= 0.12.13) were not met:

Requested 'spice-protocol >= 0.12.13' but version of spice-protocol is 0.12.12

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

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