with protobuf version >= 22, shouldn't this be solved by simply doing

find_package(Protobuf REQUIRED CONFIG)

that should look up /usr/lib64/cmake/protobuf/ProtobufTargets.cmake
(or something like that)
which will define a target protobuf::libprotobuf with a bunch of INTERFACE_LINK_LIBRARIES ...

Thank you, Tor.

Hi OCA Admin,

Would you be so kind to answer Tor's VERY valid question ????

Thank you in advance .....

Hi Tor~

In fact, the comment in cmake/protobuf.cmake already mentions:
` ` `
# We cannot use the IMPORTED libraries defined by FIND_PACKAGE above,
# protobuf::libprotobuf may have INTERFACE properties like -std=gnu++11
# and that will break the build since we use -std=c++20
` ` `

This should explain your question about find_package.

ah yes, that was a broken build on MacOS, where system headers had ifdefs hiding C++17/C++20 features.

What Linux version are you using?

kernel 6.6, gcc-12.3.1

thanks, but my intention was:
what Linux system has system protobuf >= 22, so that I can test  my cmake code?

Hi Tor~

As far as I know, protobuf 22+ is available in both OpenCloudOS Stream and OpenSUSE Tumbleweed distributions. 
I compiled the verification in a Linux environment with OpenCloudOS Stream (ocs, similar to CentOS Stream 9, using rpm/dnf).

The following is the ocs image download address, if you need to install and verify:

Thank you, Tor.

These are the issues that have to be resolved by the reporter.

Documented fix as follows in the MySQL 8.0.40, 8.4.3, and 9.1.0 changelogs:

    It was not possible to build MySQL using Protobuf 22 or later.

    Our thanks to Gordon Wang for the contribution.

Closed.

Thank you, Jon.
