error: 'enable_if_t' in namespace 'std' does not name a template type

Working with VScode:

framework = arduino

lib_deps = yoursunny/esp32cam

std::enable_if_t is available since C++17.
You get this error if you are compiling in C++11 or C++14 mode.
Please update compiler flags to use C++17 or later.
