- 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
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.
This should make all symbols that are not marked otherwise have hidden
visibility. There still may be exposed symbols if marked with respective
attributes.
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
The CMake buildsystem should be completely reviewed to properly match
what is done by SCons, instead of making its own arbitrary decisions on
how godot-cpp should be compiled.
Currently the SCons setup doesn't include warning options, so CMake
shouldn't either. Options similar to upstream Godot's SCons setup could
be added, and then replicated for CMake.
Makes all include directories consistent.
Turns GODOT_CPP_SYSTEM_HEADERS ON by default since that's what was already being done for ${GODOT_GDEXTENSION_DIR}.
From the cmake docs:
"This may have effects such as suppressing warnings or skipping the contained headers in dependency calculations (see compiler documentation). Additionally, system include directories are searched after normal include directories regardless of the order specified."
Addresses part of #999
Changes the `<godot/gdextension_interface.h>` include to simply
`<gdextension_interface.h>`.
Refactor and better document the SCons and CMake logic around setting
the paths to the header and API JSON file.
Non-exhaustive list of case-sensitive renames:
GDExtension -> GDNative
GDNATIVE -> GDEXTENSION
gdextension -> gdnative
ExtensionExtension -> Extension (for where there was GDNativeExtension)
EXTENSION_EXTENSION -> EXTENSION (for where there was GDNATIVE_EXTENSION)
gdnlib -> gdextension
gdn_interface -> gde_interface
gdni -> gde_interface
- 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
* Attach debug flags to the target and mark as `PUBLIC`. This will allow all
projects that use bindings not to add the same defines manually.
* Use generator-expressions to support multiconfig generators (such as
MSVC).
* Remove excplitic `NDEBUG` and `_DEBUG` flags, CMake handles it
automatically.
