Change cmake_minimum_required to match actual requirements This is because target_link_options was added in v3.13 So this wouldn't build with cmake v3.12 Likewise in CMAKE_CXX_STANDARD only supports value of 17 starting with cmake v3.9 So the test wouldn't build properly with cmake v3.6

Updated cmake to the new nativescript 1.1

Re-Structure cmake solution to be closer to the scons solution. 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. https://stackoverflow.com/questions/74426638/how-to-remove-rtc1-from-specific-target-or-file-in-cmake https://discourse.cmake.org/t/how-do-i-remove-compile-options-from-target/5965 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. (cherry picked from commit 2402a044ebc2189f6c725b9a64c66c9bc2e5c616)

# I know this doesn't look like a typical CMakeLists.txt, but as we are
# attempting mostly feature parity with SCons, and easy maintenance, the closer
# the two build systems look the easier they will be to keep in lockstep.

# The typical target definitions are in ${PROJECT_SOURCE_DIR}/cmake/godotcpp.cmake
{cmake} Updates for target-based approach - instead of setting globals which can effect other projects including this as a subdirectory, set them on the target if possible - add "CONFIGURE_DEPENDS" to GLOBs to check for changes - update required CMake version to 3.12 (still ancient - 2018) to support these
