- Added to .gitignore CMakeUserPresets.json
### Configuration:
- Changed python command to use single quotes to make build output log more legible.
- Added GODOT_DEV_BUILD to allow differentiation of debug or Release builds.
- Added find logic for macos Cocoa library
### godot-cpp Changes
- godot-cpp-test is changed to be incorporated into the cmake build as a target.
- Duplicated godot-cpp target into [template_release, template_debug, editor]
- Created {platform}.cmake files mirroring the style of the SCons build.
CMake has a feature called generator expressions for its configuration variables that are evaluated at build time. This allows multi-configuration build systems to properly evaulate options. for msvc, xcode and nijna multi-config.
- Moved configuration options to generator expressions with the notable exclusion of OSX_ARCHITECTURES.
- Remove CMAKE_BUILD_TYPE from msvc CI target as Multi-Config generators ignore it
### godot-cpp-test Changes
- Removed majority of the cmake code, now that the godot-cpp project is setup, the majority of the flags will be propagated as transient dependencies
- Marked with EXCLUDE_FROM_ALL so that it isn't built as part of the 'all' target
- Updated ci to build the godot-cpp-test target from the root directory using cmake
- Tests passing for Windows, Linux, and Macos builds.
### Documentation
Updated with new information
Added Emscripten example
Added Android example
Due to how caches are accessed this cache is almost useless, it only
matters if it is from the same branch or a base branch, and is identical
between branches, so caching it just clutters the build cache
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-cmakehttps://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.
Required since Godot 4.3, which is also the first Godot version with
wide WASM gdnative support (previous versions were Chrome-only, and very
brittle).
Visual Studio projects are multi-config projects like Ninja-MultiConfig which means you can't set the configuration at configure time as there are multiple, it always chooses the first one by default when not specified in the build command.
Instead of this:
cmake -DCMAKE_BUILD_TYPE=Release -G"Visual Studio 17 2022" .
cmake --build . --verbose
It should be this
cmake -G"Visual Studio 17 2022" .
cmake --build . --verbose --config Release
Update ci.yml
Because the current build system doesnt use generator expressions for multi config builds, both the CMAKE_BUILD_TYPE and the build --config options need to be set
