Build failure -- conflict between libcups ppd.h and libppd ppd.h?

[Prototyped]

I'm attempting to build an OCI container of ghostscript-printer-app using podman/buildah and am stuck at trying to build libppd.

I have:

• installed libcups2-dev from Debian bookworm, which includes CUPS 2.4.2 devel files (including cups-config).
• using this, checked out and installed libcupsfilters 2.0.0 from the GitHub repo.
• attempted to build libppd 2.0.0 from the GitHub repo:

What have I done wrong? I've largely been following the snap definition for the build, except that I've picked Debian bookworm's prebuilt libcups2-dev and ghostscript packages rather than rebuilding them myself.

$ podman build --platform=linux/arm/v7 -t gurdasani.com/ghostscript-printer-application/ghostscript-printer-application-splix:latest .

Ah, apparently the partial installation of cups is essential to build success. Would it make sense to update INSTALL.md in this repo, where it just says the following in passing, to include explicit details in how to partially install cups as a prerequisite?

Dependencies

• libcups of CUPS 2.2.2 or newer

This is what I ended up putting in my Dockerfile as an additional build stage:

That procedure does not make any sense because:

• build procedure needs to be OK without root permission (all distros packaging procedures shuld be possible to execute from non-root account)
• should be able to build libppd without fiddling in installed image of the packaging/build env (just installation of distro devel packages)
