   I am adding the ability to run the tests with previous versions of Proton, and being able to use the benchmark code with separately compiled proton installation. Currently I am aiming at Proton 0.19.0+.
   
   It is helpful to compile Proton with {{`-DCMAKE_INSTALL_RPATH_USE_LINK_PATH=TRUE -DENABLE_WARNING_ERROR=OFF`}} for this, if you use new compiler (warnings) or if you have openssl and cyrus in nonstandard location (rpath).
   
   My CMakeLists.txt for this usecase looks like this
   
   ```
   cmake_minimum_required(VERSION 3.0)
   project(benchmarks)
   
   set(CMAKE_CXX_STANDARD 11)
   set(CMAKE_CXX_STANDARD_REQUIRED ON)
   set(CMAKE_CXX_EXTENSIONS OFF)
   
   # -DCMAKE_INSTALL_RPATH_USE_LINK_PATH=TRUE
   find_package(Proton 0.18 REQUIRED COMPONENTS Core Proactor)
   find_package(ProtonCpp 0.19 REQUIRED)
   
   include_directories(${Proton_Core_INCLUDE_DIRS})
   
   # link everything everywhere
   link_libraries(${Proton_LIBRARIES})
   link_libraries(${ProtonCpp_LIBRARIES})
   # workaround, proton cpp .so does not set rpath for $ORIGIN, so these wouldn't be found otherwise
   link_libraries(${Proton_Core_LIBRARIES})
   link_libraries(${Proton_Proactor_LIBRARIES})
   
   # in-tree benchmarks link these libs, create dummy empty ones
   add_library(qpid-proton OBJECT IMPORTED)
   add_library(qpid-proton-cpp OBJECT IMPORTED)
   
   add_subdirectory(../c/benchmarks cbenchbin)
   add_subdirectory(../cpp/benchmarks cppbenchbin)
   ```
   
   With this, I can have historical charts (raw version, simply drawn in online spreadsheet). Also, I have set fixed CPU clock to 1.9 GHz, so that results are stable, but generally less than half of what can be achieved on maxed-out clock speeds. I am still not very confident about intel pstate cpu freq settings. I think what I got there now works ok...
