ConanException: First argument of CMake() has to be ConanFile. Use CMake(self)

[rwols]

I get this when issuing conan create foo/bar:

ERROR: PROJECT: Error in build() method, line 11
    cmake = CMake(self.settings)
    ConanException: First argument of CMake() has to be ConanFile. Use CMake(self)

Note I'm on conan 0.30. I'm running the release/3.3.0 branch.

Yes, this has changed in the last conan release, and the recipe is a bit outdated. I am going to correct it asap, but if you are using it from bintray (conan-transit), I don't know if I will be able to update it. Thanks for reporting!

I have updated both the git branch release/3.3.0 and the bintray conan-transit recipe. Please tell me if it works, thanks!

This brings me a bit further :) But now protoc seems to complain:

/home/raoul/.conan/data/protobuf/3.3.0/qipc/snapshot/package/a22947addb79cf353b6edadaed388d4998a1af6f/bin/protoc: error: '/home/raoul/.conan/data/protobuf/3.3.0/qipc/snapshot/package/a22947addb79cf353b6edadaed388d4998a1af6f/bin/.libs/protoc' does not exist
This script is just a wrapper for protoc.
See the libtool documentation for more information.

This is at the test package step:

Myabe the FindProtobuf.cmake helper is finding another protoc in your system? (I just tested in Windows).

Also, I am not a big fan of find-cmake scripts, what I want to do is to actually create an independent package for protoc, because it also has some issues for dynamic libraries. I will be updating this package once we are able to release conan 1.0, hopefully soon.
