OS: FreeBSD 12.2

Commit: dd8b63

After "autoreconf -i" I get:

"Makefile.am:18: error: 'pkgconfig_DATA' Is used but 'pkgconfigdir' Is undefined."

I tried several previous commits but the error persists OR there are errors after "./configure"

I can only compile the 2017 version of SoX on mansr GitHub.

Can anyone help me?

Regards,

Simone
