Fix private deps

[facontidavide]

I believe that this is the correct solution (still testing)

See #1026 #1024 #1023 In BehaviorTree/BehaviorTree.CPP;

This does not fix the problem #1026 addressed.
Try this cmd. The key here is the -o */*:shared=True bit, which sets every package on the conan dep tree to be shared. That usually is a good way of hashing out missing public deps.
Under this scenario, you may still see an issue when gtest queries the test binary to register the tests. So it may be a good idea to build with tests disabled, the same linking issues show up with examples and tools.

rm -rf build
conan install . -s build_type=Release --build=missing  --settings:host compiler.cppstd=17 -o */*:shared=True
cmake --preset conan-release 
cmake --build --preset conan-release

The bt lib builds just fine, but when things that depend on it (tests, tools, examples) try to link they fail with undef symbols.
E.g.:

[facontidavide]

interesting.

Would set the conanfile.py configuration to ZMQ static help, in your opinion?

[ericriff]

I think the -o */*:shared=True on the conan CLI or conan profiles would take precedence.

And even if it works I think it would just shove the problem under the rug
