env_info for other packages depends on this pacakge about conan-protobuf HOT 4 OPEN

Hi @gasuketsu !
This is quite right. New conan version will have huge improvements with the environment variables management, so it could be a good approach to define env-vars for making tools available via PATHs, instead of relying on consumers importing files. Actually, the protobuf package protoc app might have some issues when using shared libraries due to relocation, so the LD_LIBRARY_PATH might be quite good. Especially because now the environment variables are set per package, so this reduce the risks of trouble of excessive polluting the environment.

The behavior you describe with the imports when the package is being built by conan (in the conan local cache), could be that the imported files are removed after build(). We had the issue of packages doing imports (like protoc), they were re-packaging those artifacts, which was not intended by the users. So the default is that they are removed after the build command. If someone wants to re-package them for any reason, it is simple: just copy them in the build step to a different folder.

@gasuketsu Nice to see that you are trying development versions. Be little careful with that version, it has some known bugs. We hope to publish a release candidate today, I'll write you then.

Hi! We have the release candidate ready, please help us to try it! :)

pip install conan==0.20.0rc1

@lasote @memsharded Thank you for your information.

Now I am trying 0.20.0rc1 and it gets easier to apply existing autotools based projects. Thanks!
One thing I found is, as I have commented on conan.io's issue 1015 env val PATH definition in activate.sh generated in consumer package gets increased like below by performing conan install for consumer package.
(in this example, package_info() in recipe for Protobuf/2.6.1@gasuketsu/testing appends path to package bin directory)
