The source tarball available on PyPI for krbalancing 0.5.0b0 is missing cmake/conan.cmake, which leads to the following errors when trying to build from those sources:
  CMake Error at CMakeLists.txt:20 (include):
    include could not find requested file:
      /tmp/krbalancing-0.5.0b0/cmake/conan.cmake
  --  project version 0.5.0b0
  CMake Error at CMakeLists.txt:33 (conan_cmake_configure):
    Unknown CMake command "conan_cmake_configure".
  -- Configuring incomplete, errors occurred!
It seems like 0.5.0b0 was published on PyPI by @dilawar using changes in the the open pull request #22 ?
