grpc++-dev doesn't install gRPCConfig.cmake

[Joonas Harjumäki]

Because libgrpc++-dev-1.30.2-3 doesn't install gRPCConfig.cmake file, it is not possible to use find_package(gRPC) cmake command.

Not having this is super inconvenient. Please include the cmake config files.

Status changed to 'Confirmed' because the bug affects multiple users.

No plan to release the fix?

I think this is a packaging problem and just adding one line in debian/debian/libgrpc-dev.install resolves this issue.

I also came across this bug and indeed it's very inconvenient. Now I will have to manually install it.

Only Jammy suffers from this, as Mantic+ contains the change to add the cmake files. This does look like it could be remedied with a single line change as alluded by Masanori in comment #4. The one line change is a partial of the debian commit when doing a libary transition[0].

I'm building a test package right now with that one line change to see if it's that simple.

This bug does specifically mention libgrpc++-dev, but I only see the cmake files added in libgrpc-dev in the debian archives, so I assume that's good enough to only include the cmake files in libgrpc-dev and not libgrpc++-dev.

I haven't updated this for a bit, but I tried the aforementioned change in comment #7 in this PPA and it did not build - https://launchpad.net/~mitchdz/+archive/ubuntu/lp1935709-grpc-cmake-dev-files/+packages

It is still missing in 2024-07.
