configure: error: Package requirements (mdds-2.1) were not met:

No package 'mdds-2.1' 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 MDDS_CFLAGS
and MDDS_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
