Explicitly set C11 and C++14 via the CMake variables (#141)

Browse source 
* Explicitly set C99 and C++14 via the CMake variables

* Enable passing CMAKE_C_STANDARD and CMAKE_CXX_STANDARD externally

* Use add_compile_options

* Be more specific about the compiler, independent from the OS

* Check compiler, not OS. Use add_compile_options instead of CMAKE_C_FLAGS and CMAKE_CXX_FLAGS

* add_compile_options() takes a list, not a string

* switch to c11 because of redefinition warnings

avoid typedef redifinition warning on macos

remove todo, compiler come from redefinition of typedef
