BUG: cmake_minimum_required must be the first command

Browse Source 
https://cmake.org/cmake/help/v3.5/command/project.html

Note: Call the cmake_minimum_required() command at the beginning of the
top-level CMakeLists.txt file even before calling the project() command.
It is important to establish version and policy settings before invoking
other commands whose behavior they may affect. See also policy CMP0000.
