remove cruft, fix BUILDING and README

!! NOTE !! I MESSED UP THIS COMMIT BY FORGETTING TO MAKE A NEW BRANCH AND FORGETTING TO PULL SO IT'S A RE-MERGE

* feat: attempt to make a windows runner

* fix: typo

* fix: runners, separate linux/windows, change BUILDING a bit

* feat: add sccache to windows build

* chore: rip out buildsystem for now, add ccache for windows

* fix: make win runner actually use ccache

* fix: install ninja (doesn't come preinstalled somehow)

* fix: use action for ninja instead of vcpkg

* fix: linux action, weird linker error

* fix: another attempt at fixing the linux runner

* fix: linux builds, output paths

* fix: github action paths

* remove cruft, fix BUILDING and README

-Building ~~should be relatively straightforward~~ is a somewhat arcane process. As of now, there's nothing currently hooking into the GDExtension
-bindings that'd work, so building is just an exercise in filesize and checking nothing's exploded.
+## Note:
+We have CI set up for Winter, so you should be able to download the latest libraries without needing to build.
 
-Note that libcurl is required currently to build as well.
 
+## Building
+Building should be relatively straightforward, libcurl is needed as a dependency - all other deps are handled by cmake.
 
-# ON WINDOWS:
+However, do add the following cmake flags when configuring:
+
+``-DGODOT=1 -DGODOT_GDEXTENSION_DIR="gdextension" -DGODOT_CPP_SYSTEM_HEADERS=ON``
 
-install libcurl from vcpkg (MAKE SURE THEY'RE X64)
+These enable the Godot bindings extension - set ``-DGODOT=0`` to build the headless module instead.
 
-make a build folder, ninja probably works if you're 100% sure it's using c++20 but use vs otherwise
+# ON WINDOWS:
 
-``cmake .. -DCMAKE_TOOLCHAIN_FILE=something-goes-here -DCMAKE_BUILD_TYPE=Debug``
+Note that only MSVC seems to work, though you can use MSBuild or Ninja. Also seemingly only Debug build types work.
 
-build. it should... build if everything's gone to plan.
+Fish out the .dll and associated libraries (libcurl and zlib generally) and put them in the Belmont repository in bin/.

-## Requirements
-
-- Git CMD (https://git-scm.com/download)
-
-- CMake (CMD/GUI) (https://cmake.org/download/)
-
-- A IDE (Visual Studio, XCode, etc)

-Coldfield relies on Godot 4.0 for gdextension. everything is automated through CMake, so configuring the project through CMake-GUI will handle grabbing dependency's, creating the solution, etc.
