Christian Heimes added the comment: gdbmmodule and dbmmodule need special treatment anyway. macOS has dbm-API build into libc. Linux has either libgdbm_compat, libndbm, or libdb. The --with-dbmliborder makes it even more interesting. Users can override in which order they want to probe for

Ned Deily added the comment: SGTM,2 This all sounds great. I think a goal here should be to remove all header and lib file searching from setup.py as that has always been a bug magnet. Perhaps one workaround for those libs that don't (yet) provide .pc files would be for us to supply

Christian Heimes added the comment: We can detect majority of our dependencies with pkg-config. The use of pkg-config has some benefits: * Distro's provide the .pc files in their -dev / -devel packages. The presence of a .pc file indicates that all development dependencies are available. *

[issue45573] Use pkg-config autoconf macros to detect flags for Modules/Setup

New submission from Christian Heimes : pkg-config [1] is a standard tool on Linux and other platforms to detect presence of dependencies as well as to figure out which compiler and linker flags they require. Development packages provide a .pc file, e.g. ncurses provides a ncursesw.pc file.
