pkg-config can not resolve dependencies

[DmitriiKuchevskii]

What version of protobuf and what language are you using? 33.0 Language: C++

What operating system (Linux, Windows, ...) and version? Linux (Ubunut)

What runtime / compiler are you using (e.g., python version or gcc version) clang 21

What did you do?

1. build from source using CMake and install to any DIR
2. set PKG_CONFIG_PATH to the DIR/lib/pkgconfig
3. execute pkg-config protobuf --cflags or pkgconf protobuf --cflags
4. Additional step is to execute pkgconf protobuf --digraph

What did you expect to see The output should be there within seconds The dependencies graphs should have a sane size

What did you see instead? pkg-config/pkgconf got stuck for minutes (I've been waiting for around 15) The graph is insanely large (>2 millions nodes)

I'm honestly not an expert with any of pkg-config or pkgconf, but to me it looks like some kind of cyclic dependencies somewhere in CMake files

[DmitriiKuchevskii]

Solved by using the latest pkgconf While it works, it still looks like some kind of bug in deps ( a lot of repeated flags)

 ./installed/bin/pkgconf protobuf --cflags

This may be the result of cyclic dep in our cmake build files. We will investigate that separately. We will accept contributions in the meantime.
