configure: error: Package requirements (libixion-0.14 >= 0.14.0) were not met:

No package 'libixion-0.14' found

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

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