* Ignore cmake intermediate build dir
* Fix C++ language version in cmake build scripts
* Set a default SDL2_ROOT_DIR value for macOS in cmake scripts
* Fixed macOS SDL framework linking in cmake scripts
* Added macos-cmake target for CI builds in github workflows
* Use C++17 for building Tests instead of 20, since we build them with VS2019 in some jobs
The goal here is to replace the current (slightly broken) Travis + Appveyor setup with something that covers more cases and is a bit better supported and easier to maintain. This hopefully helps us catch cross-platform issues quicker. For example, the linux and clang compilation issues that have existed for a while could have been caught if we were building those targets in CI.
This adds a build script that builds the following configurations for every repo commit and PR:
macOS, premake, Debug
macOS, premake, Release
linux, premake, gcc, Debug
linux, premake, gcc, Release
linux, premake, clang, Debug
linux, premake, clang, Release
linux, cmake, Debug
linux, cmake, Release
windows, premake, vs2019, Debug
windows, premake, vs2019, Release
windows, premake, vs2022, Debug
windows, premake, vs2022, Release
windows, cmake, vs2019, Debug
windows, cmake, vs2019, Release
windows, cmake, vs2022, Debug
windows, cmake, vs2022, Release
It also builds and runs the catch tests executable in the following configurations. A failed test will fail the build.
macOS, premake, Debug
linux, premake, clang, Debug
windows, premake, vs2022, Debug
It doesn't currently build cmake on macOS because there is a one blocker there (#577). We could also add additional builds like cmake with both clang and gcc on linux, but for now this is much better coverage than we have currently.
