What is pkg-config WRT macports

[Christoph Kukulies]

I’m stumbling accross some build errors in a package named „blackmagic“:

$ git clone https://github.com/blacksphere/blackmagic.git
Cloning into 'blackmagic'...

remote: Counting objects: 100% (5/5), done.

$ cd blackmagic/
$ make PROBE_HOST=hosted
 GIT include/version.h
Package libftdi1 was not found in the pkg-config search path.
Perhaps you should add the directory containing `libftdi1.pc'
to the PKG_CONFIG_PATH environment variable
No package 'libftdi1' found
Package hidapi-libusb was not found in the pkg-config search path.
Perhaps you should add the directory containing `hidapi-libusb.pc'
to the PKG_CONFIG_PATH environment variable
No package 'hidapi-libusb' found

Now I’m wondering: is that pkg-config a part of macports or in other words, can macports help in supplying the issing packages?

Merry Christmas, Happy Seasons,

Christoph
