AFAIK check_symbol_exists is used for preprocessor symbols. check_function_exists looks for C functions, not C++. Also notice, that older C++ standard libraries and non-compliant C++ compilers don't use the namespace std. You might want to have a look at CMakeBackwardCompatibilityCXX.cmake or the various other modules it uses.
