Error when cmake: Your C++ compiler does not support C++11

[yan-map]

Hello!

I'm struggling to build the project on command cmake .. I have this error list:

CMake Deprecation Warning at CMakeLists.txt:1 (cmake_minimum_required):
  Compatibility with CMake < 3.5 will be removed from a future version of
  CMake.

  Update the VERSION argument <min> value or use a ...<max> suffix to tell
  CMake that the project does not need compatibility with older versions.

CMake Warning (dev) at cmake/FindGLPK.cmake:62 (MARK_AS_ADVANCED):
  Policy CMP0102 is not set: The variable named "GLPK_BIN_DIR" is not in the
  cache.  This results in an empty cache entry which is no longer created
  when policy CMP0102 is set to NEW.  Run "cmake --help-policy CMP0102" for
  policy details.  Use the cmake_policy command to set the policy and
  suppress this warning.

CMake Warning (dev) at CMakeLists.txt:55 (if):
  Policy CMP0054 is not set: Only interpret if() arguments as variables or
  keywords when unquoted.  Run "cmake --help-policy CMP0054" for policy
  details.  Use the cmake_policy command to set the policy and suppress this
  warning.

  Quoted variables like "MSVC" will no longer be dereferenced when the policy
  is set to NEW.  Since the policy is not set the OLD behavior will be used.
This warning is for project developers.  Use -Wno-dev to suppress it.

Thank you!

Could you try again with the latest master? I replaced the old manual logic to set up C++-11 by set(CMAKE_CXX_STANDARD 11).

I am assuming this issue is now fixed with the latest master.
