Are you sure about this?

To my knowledge, the pkg-config mechanism tells you what packages are
installed via a Linux distribution's package management, such as apt.

However, if the user chooses to install a different version of a library
locally, using environment variables or parameters to `./configure` to
point the compiler there, then my guess is that relying on pkg-config
would seriously screw up things.


Unless pkg-config reliably addresses that issue, in my opinion our first
attempt should be to try and pry the relevant information from the very
files that will be accessed during compilation, i.e. the header files.
