cmake_minimum_required(VERSION 3.10...3.17)

#[=======================================================================[.rst:

CMake Version requirements

--------------------------

To enable use of the emscripten emsdk hack for pseudo shared library support

without polluting options for consumers we need to use the

CMAKE_PROJECT_<PROJECT-NAME>_INCLUDE which was introduced in version 3.17

For more information check cmake/emsdkHack.cmake

SCons Compatibility

-------------------

There is an understandable conflict between build systems as they define

similar concepts in different ways. When there isn't a 1:1 relationship,

compromises need to be made to resolve those differences.

As we are attempting to maintain feature parity, and ease of maintenance, these

CMake scripts are built to resemble the SCons build system wherever possible.

Where they are not, we will attempt to document common difference in

the docs (https://docs.godotengine.org/en/latest/tutorials/scripting/cpp/build_system/cmake.html)

and platform specific differences in their respective

cmake/<platform>.cmake file.

The file structure and file content are made to match, if not in content then

in spirit. The closer the two build systems look the easier they will be to

maintain.

Where the SCons additional scripts in the tools directory, The CMake scripts

are in the cmake directory.

For example; the tools/godotcpp.py is matched by the cmake/godotcpp.cmake file

.. highlight:: python

cpp_tool = Tool("godotcpp", toolpath=["tools"])

cpp_tool.options(opts, env)

The CMake equivalent is below.
