+Subject: [PATCH] [cmake] disable NEON runtime check on clang-cl
+
+When enabling runtime NEON checking for clang-cl, the linker would error out with `undefined symbol: __emit`, since clang doesn't actually implement this instruction. Therefore it makes sense to disable the runtime check by default on this platform, until either this is fixed or a clang-cl compatible intrinsic check is added (I don't have enough knowledge of MSVC to do this)

+There are two main applications, an SDL-based app (`eden-cli`) and a Qt based app (`eden`); both accept the same command line arguments.

 - `./eden <path>`: Running with a single argument and nothing else, will make the emulator look for the given file and load it, this behavior is similar to `eden-cli`; allows dragging and dropping games into the application.
- `-g <path>`: Alternate way to specify what to load, overrides. However let it be noted that arguments that use `-` will be treated as options/ignored, if your game, for some reason, starts with `-`, in order to safely handle it you may need to specify it as an argument.
- `-f`: Use fullscreen.
- `-u <number>`: Select the index of the user to load as.
- `-input-profile <name>`: Specifies input profile name to use (for player #0 only).
+- `--debug/-d`: Enter debug mode, allow gdb stub at port `1234`
+- `--config/-c`: Specify alternate configuration file.
+- `--fullscreen/-f`: Use fullscreen.
+- `--help/-h`: Display help.
