Hi,

I am trying to create a static lib with the message definitions to be share across multiple CMake projects. At the moment, I have:

A Conan.io package with protobuf pre-comiled into static libs.
A CommonDefinitions project (with a dependency to the protobuf package)

From which I create a CommonDefinitions conan.io package containing the CommonDefinitions static library
Project include a test Executable which uses the static library

A EndUser project (with a dependency to the CommonDefinitions package and the protobuf package)

Now, the test executable of the CommonDefiniitons project works as expected and has access to the CommonDefinitions messages. However, the EndUser project is not able to link, it complains about missing references to protobuf static libraries, even though I also include the protobuf package in the EndUser target_link_libraries project as well.

Does anyone have an idea or had a similar problem?

Thanks

Here are the linker traces:

Perhaps look at the link command and see if it includes the protobuf libraries as you expect, or post it here.
