Hello, I am looking at:
https://cmake.org/cmake/help/v3.14/prop_tgt/CXX_STANDARD.html and I see that I can pass 20, for c++20. However I do not have that in my compiler, I only have c++2a and gnu++2a, this means that CMake goes back to c++17 and macros like __VA_OPT__: https://gcc.gnu.org/onlinedocs/cpp/Variadic-Macros.html can't be used. I know that all this should work, because I can compile myself a small test piece of code with: g++ code.cxx -o code -std=c++2a so the problems is CMake. Is there a way to go around this? Cheers.
