pkg-config with goav cannot find where to set path

[8v-piper]

Hi apologies for the noob question, I have tried reading documentation and web search.
No matter what i try i keep getting the following error:

pkg-config --cflags -- libswresample libswresample

error $GOPATH: no library found in $GOPATH: libswresample
error github.com: PKG_CONDIF_GITHUB not exported, skipping github.com lookup
error $PKG_CONFIG_PATH: open libswresample.pc: The system cannot find the file specified.
error : no library found in $GOPATH: libswresample
pkg-config: exit status 1

please help or point to a tutorial

I think that I encountered a similar issue: pkg-config was not able to find the .pc file even with the $PKG_CONFIG_PATH env var properly set (pkg-config ignore the value and always search in /usr/local/share/pkgconfig). I ended up by creating a sym link from the real path to the one which is configured by default for pkg-config.

ln -s /usr/lib/x86_64-linux-gnu/pkgconfig /usr/local/share/pkgconfig

This worked for ubuntu-22.04.
