* cmake+ci: run clang-tidy
* Remove DESCRIPTION from LEGO1/LegoOmni.mingw.def
* Add initial .clang-tidy and fixes
* fix file perms
* Comment out DESCRIPTION
* Remove LegoEntity::~LegoEntity and MxPresenter::~MxPresenter from mingw's LEGO1.def
* Looks like clang is allergic to the libs in the directx5 SDK
* Update .clang-tidy
* Fix typo in .clang-tidy
* Attempt to generate an action error
* Revert "Attempt to generate an action error"
This reverts commit 96c4c65fed.
* cmake: test with -Wparentheses + optionally with -Werror
* ci: -k0 is a Ninja argument
* Use -Werror only for msys2 builds
* cmake: only emit warnings for specific warnings
* cmake: and don't do -Werror/-WX anymore
* Fix warnings
* Fix mingw warnings
