Normalize CMake paths

[BaconOFBurger]

Hi so today I tried generating C++ bindings for godot with CMake and I've stumbled on an issue around there.

Basically add_library would fail on windows because paths seems to not be normalized, I managed to fix the issue by adding these lines of code before the add_library call

string(REPLACE "\\" "/" PROJECT_NAME      "${PROJECT_NAME}")
string(REPLACE "\\" "/" SOURCES           "${SOURCES}")
string(REPLACE "\\" "/" SOURCES_FILE_LIST "${SOURCES_FILE_LIST}")
string(REPLACE "\\" "/" HEADERS           "${HEADERS}")
string(REPLACE "\\" "/" HEADERS_FILE_LIST "${HEADERS_FILE_LIST}")

I'm not very familiar with github so I'm unsure how to request a change so ill just post the fix there and let someone do it for me.
