Make C++ standard to be enable from cmake settings: User will be able choosing C++ language standard by selecting cmake variable BUILD_CPP_STANDARD. For correct working, CMAKE_CXX_STANDARD cmake built-in variable should be available. To enable CMAKE_CXX_STANDARD, minimum CMAKE version has been updated to 3.1. Available next standard items: C++11 C++14 C++17 C++20 C++23 This issue consists from several steps to achive main goal: 1) Configuratiuon, CMake - allow selecting C++ standard. 2) Require minimum CMAKE version 3.1 (for enabling CMAKE_CXX_STANDARD). 3) More flexible CMAKE_CXX_COMPILER_ID identification (fixups previous commit!) 4) Add description of new CMAKE variable `BUILD_CPP_STANDARD` into documentation. 5) Update CMAKE requirements in documentation. 6) Set C++11 standard for several projects.
