Now that the library does not provide any CMake find-modules, it is useless to alter the global. Besides, the only way for a higher level integrating project to provide its own dependency resolution mechanism (Conan, local source tree, etc)relies on appending to CMAKE_MODULE_PATH prior to locating packages. Sdl2pp overriding the variable breaks this mechanism and therefore can only locate a globally installed copy of SDL, which is often inconvenient or plain impossible.
