In Ubuntu: ietf@ietf-VirtualBox:~/picotls$ cmake . -- The CXX compiler identification is unknown -- Check for working CXX compiler: /usr/bin/cmake -- Check for working CXX compiler: /usr/bin/cmake -- broken CMake Error at /usr/share/cmake-3.16/Modules/CMakeTestCXXCompiler.cmake:53 (message): The C++ compiler
