Conditional audio flags

[shih1]

• updated juce 7 -> juce 8.0.4 since I'm running osx 15
• new flag SST_JUCEGUI_SKIP_AUDIO which can be override downstream to add or to skip the audio flags.

baconpaul said in discord:

It always zeroes out CURL and WEB_BROWSER. Those have to stay defined
It has an option called "SST_JUCEGUI_SKIP_AUDIO" which defaults to true
if it is true you add those definitions for jack -> directsound
surge sets it to false in lib.cmake before including

I think he meant

if it is **FALSE** you add those definitions for jack -> directsound

cus - y'know -

"skip audio" mean "don't add audio flags"
NOT "skip audio" means "add flags"
horray for confusing double negatives

but opening it up to discussion.

[baconpaul]

should the default be false to retain old behavior?

[baconpaul]

but since the examples build I think it is fine as is. Let's not insert them unless upstream wants them by default. then no surge change required even! if you agree let me know and we can merge this

[shih1]

Im a subscriber to less is more

esp because this PR is bc macros were redefined, and because this library will be a common upstream dependency, less macro definitions will prevent future issues?

forward progress! i say merge as is but i wouldn't die on this hill.

[baconpaul]

You know, most of the upstream ones are in the clap juce shim branch anyway. I think it is just vestigial. So yeah leave it as is.

[shih1]

before merge i want to point out that i have no idea if this upgrade will break any downstream dependencies.

[baconpaul]

It won't. We also CI test with 7 and 8 so this is just a default.

[baconpaul]

So merged away! If you want to pull the surge side we can now test CI then merge.

Then I'd say next step is replace the fx knob class with sst::jucegui::components::Knob and see if you can make it all hang together
