* Downgrade minimum cmake required to 2.8
In some embedded system, the cmake version is still 2.8.x. So use
SET instead of APPEND to adapt to more envir.
* Set cmake minimum required version to 2.8.12
* Adapt for cmake 2.8.12 using target_compile_options instead of feature
* Fix openmp compiling error on cmake 2.8.12
std::{unary|binary}_function<> are deprecated in C++11 and removed in C++17.
Actually, these were unnecessary in general. In the C++98/03 era, many user-
defined function object classes derived from these base classes in an attempt
to imitate STL conventions. However, STL containers and algorithms have never
required such inheritance (or the typedefs that they provide). Only the
function object adaptors (like bind1st()) needed such typedefs. Currently,
there are no uses of function object adapters in our codebase, so we can
eliminate the inheritance completely.
