@victorreijgwart Fixed the static member linker error.
The reason for is that inline static variable definition is only allowed in C++17 or after (similar to normal static members), whereas your cmakelists contains std=c++11. Depending on the compiler optimization, it might however auto-generate these or maybe you have some other specifications for your build, this is potentially why it didn't show up on your machine. Anyway, I added the standard c++11 definition to the .cpp. Cf.
