2.0.0: loop in build dependencies

[kloczek]

Describe the bug

Looks like it is th loop in build dependencies because libppd requires pkgconfifig(libcupsfilters) and on building cups-filters 2.0.0 is required pkgconfifig(libppd). 🤔 Both build time requirements are unconditional so it is not possible to build one of those components first without second one and after building second one rebuild first one with enabled build stage dependency of second one.

https://github.com/OpenPrinting/libppd/blob/2.0.0/configure.ac#L122-L125

https://github.com/OpenPrinting/cups-filters/blob/2.0.0/configure.ac#L120-L123

Probably only way to build libppd is to build it against pkgconfifig(libcupsfilters) 1.x and than build libcupsfilters 2.x and again rebuild libppd however after that it is not possible to bootstrap both components.

[kloczek]

No I was wrong. It is not possible to build libppd against pkgconfifig(libcupsfilters) 1.x

log.h is not part of the pkgconfifig(libcupsfilters) 1.x.

libcupsfilters should not depend on lippd, if so, it is a bug, like something forgotten in configure.ac.

You want to build cups-filters 2.0.0. To do so build libcupsfilters 2.0.0 (libcupsfilters and cups-filters are separate repos now) first, then libppd 2.0.0, and after that cups-filters 2.0.0.

[kloczek]

Closing. I didn't notice that separation of libcupsfilters 2.0.0.
