Split examples

[Daft-Freak]

#744, but moving everything. More discussion over there. WIP.

[Daft-Freak]

There's certainly a lot of duplication in the docs... and a lot of the phrase "Set up the 32Blit Makefile from the root of the repository", I feel like that needs rewording somehow.

[Daft-Freak]

Will squash the hardware-test undelete into the delete to not mess up history. (Unless we don't keep them here).

Could move the launcher next to those too... 🤔

[Gadgetoid]

I really need to stop crashing into bed in the evenings and get onto 32blit/32blit-examples#1 😬

[Daft-Freak]

Ah, this is being held up by documentation isn't it?

[Gadgetoid]

This is being held up by documentation and that's entirely my fault. It's been gnawing at my brain all this time, but I haven't had an opportunity to sort it. 😬

[Daft-Freak]

Well, it's not like I didn't completely forget about this myself...

(Too busy hacking on emulators apparently.)

[Gadgetoid]

Not me finding examples in the SDK very, very useful again... 😆

[Daft-Freak]

Anything can be "in" the SDK with enough add_subdirectorys hacked in. 😆

(I may have a few extras added most of the time)

[Daft-Freak]

🤔

if(EXISTS ${CMAKE_CURRENT_LIST_DIR}/examples/CMakeLists.txt)
    add_subdirectory(examples)
endif()

2. clone 32blit-examples to examples
3. Pretend nothing changed

[Gadgetoid]

Wait haven't we just reinvented git submodules? 🤔

[Daft-Freak]

Uh kinda, but specifying a specific commit of the examples doesn't seem useful.

(Mostly thinking of a way to make this change slightly less huge)

[Gadgetoid]

Yeah that's a good point, and was nagging away at the back of my mind 😆

[Daft-Freak]

master...Daft-Freak:32blit-beta:split-examples-2 + 32blit/32blit-examples#3 seems to work. Didn't even delete the .sln, it just explodes if the examples aren't there...
