Fix hyperdex python build.
Clean up dependencies.
Remove dot '.' from dependency.

This breaks because of https://github.com/hashdist/hashdist/issues/208
Merge pull request #176 from teh/master

Add hyperdex to hashstack.
Closes #159 by making the cmake_package feature complete.

The cmake_package by default sets CMAKE_INSTALL_RPATH, and
CMAKE_INSTALL_RPATH_USE_LINK_PATH by default. It also uses the global
debug flag to determine the value for DCMAKE_BUILD_TYPE.

Also for CMake builds we need to setup CMAKE_PREFIX_PATH with the
directories of our dependencies, this allows CMake projects calls
to find_* to first look at hashdist build versions first.
Remove all redundant values from cmake packages.
