Hello, thank you for sharing your work. I encountered this error when compiling. May I ask for you some advice?

My operating system is Ubuntu18.04 The C compiler identification is GNU 11.1.0 The CXX compiler identification is GNU 11.1.0

make_unique is an C++14 feature. Using the following directive in CMakeLists.txt fixed it for you: set(CMAKE_CXX_STANDARD 14).
