Display integer at compile time in static_assert()

Here is a simplified version of what I'm trying to do

enum First
{
    a,
    b,
    c,
    nbElementFirstEnum,
};
enum Second
{
    a,
    b,
    c,
    nbElementSecondEnum,
};

static_assert(
    First::nbElementFirstEnum == Second::nbElementSecondEnum,
    "Not the same number of element in the enums.");
/*static_assert(  
    First::nbElementFirstEnum == Second::nbElementSecondEnum, 
    "Not the same number of element in the enums." + First::nbElementFirstEnum + " " + Second::nbElementSecondEnum);*/

But I would like to be able to print the value of First::nbElementFirstEnum and Second::nbElementSecondEnum in the assert message (like in the commented version which obviously doesn't work). I have tryed using macro concatenation with "#". I also tryed using variadic templates, retrieveing with %10 each number and adding the '0' character to the value retrieved, but all I get is a constexpr char[].

So my question is how can I get my enums values to be printed in a string literal.

The most interesting topic was this one: Printing sizeof(T) at compile time But I don't want to have a warning, or decomment code to know the values.
