This is just a single step, re-arranging the code without actually changing its functionality.
new docs/cmake.md
moved the block of comments from the start of the CMakeLists.txt into the cmake.md file and converted content to markdown.
new cmake/godotcpp.cmake
Moved all exposed options into a new function godotcpp_options()
Moved configuration and generation code into godotcpp_generate()
To get all the options into the godotcpp_options() I changed the logic of GODOT_USE_HOT_RELOAD which I believe is a closer match to scons, that if the options is not set, and the build type is not release, then it defaults to ON.
I msvc builds require the default flags to be modified or it will throw errors. I have added the links to articles in the commit, but its about removing the runtime error checks /RTC1 from the CMAKE_CXX_FLAGS_DEBUG variable. This needs to happen before the files are included.

Renamed GodotCompilerWarnings.cmake to common_compiler_flags.cmake to match scons
Included files explicitly by path, as we dont need to append to the CMAKE_MODULES_PATH which effects the whole build tree.
This prevents consumers of the library from clobbering the names of the cmake include files and breaking the build.
