[wontfix][>=2.3.0] Autotools: Generated CMake config does not respect --includedir --libdir

[veprbl]

The autotools configuration allows to specify different absolute paths for various components:

./configure --prefix=/foo --includedir=/bar/include --libdir=/baz/lib

This is a feature that we use in nixpkgs to separate runtime and development parts of packages. Unfortunately, this is currently producing a cmake config file that reports invalid paths.

Downstream issues NixOS/nixpkgs#129092 NixOS/nixpkgs#128997

Confirming for --includedir= and (for some cases) of --libdir=. A clean universal fix is not trivial and the issue can be worked around on packaging level (downstream) rather easily, so it's not very high priority right now.
