Fails to build with newer cmake

[cscd98]

Setting -DCMAKE_POLICY_VERSION_MINIMUM=3.5 does fix it. Please update your CMakeLists.txt to 3.5.0

Original error:

CMake Error at CMakeLists.txt:21 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.

Second issue - installing to wrong location due to incorrect usage of variable which is not expanded into a string:
