- Add C11_COMPILE cmake option that creates a static lib instead of header-only - Add C11_INLINE macro that depends on C11_COMPILE - Split App.hpp into App.hpp and impl/App_inl.hpp - Add App.cpp that compiles App_inl.hpp into an object file - CMake modifications to handle impl headers differently for sinlge-header, headers-only, and compiled versions
