cmake fails due to missing dependency hexchat-plugin

I know it's unlikely this is still being maintained, but I thought I'd post this anyways.

Searching around, I can't seem to find anything on hexchat-plugin. No idea where to get it. Any hints?

Wait a minute... why is the script pulling from /home/linuxbrew instead of my home directory? Maybe that's related?

Hi,

hexchat-plugin.pc is provided by HexChat. This looks like Ubuntu, so you should install hexchat-dev to get it.

Yes, using non-default pkg-config can affect the search. You can try either setting PKG_CONFIG_EXECUTABLE="/usr/bin/pkg-config" on CMake command line, or add /usr/lib/x86_64-linux-gnu/pkgconfig to the PKG_CONFIG_PATH environment variable before running CMake.
