build: Allow specifying list of plugin dependencies for IDE launch schemes

[mentlerd]

Problem description

Launching ImHex from Xcode is clunky, as the main target does not depend on plugins. Therefore editing a source file, and simply launching the active Xcode scheme may result in the application using a previously built version of the file just edited.

From a build system perspective this is perfectly logical. The main executable can be built independently of any plugins, but this is very annoying UX.

Implementation description

This PR adds a new cmake boolean option IMHEX_IDE_HELPERS_MAIN_DEPENDS_ON_PLUGINS which does as the name imply.

Plugins in the build will be marked as a dependency of the main target, allowing a single-button launch from the IDE without having to think twice about which plugin was just edited.

N/A

Additional things

_tweakTargetsRecursive was mistakenly declared as a macro. This caused issues due to an early return in the implementation prematurely interrupting tweakTargetsForIDESupport.

Nothing prevents the code from working as a function, and thus it has been converted to one.

Why not use the target imhex_all instead of main ?

That will generate the required libraries, but not launch the main executable. The goal is to be able to develop without having to change schemes in Xcode constantly.

I'm confused. Doing ninja main in my terminal doesn't launch ImHex ?

It does in Xcode. That's why the entire thing is constrained in ide_helpers.cmake

Isn't there a way to make ImHex run when compiling the imhex_all task ? This sounds like a XCode issue rather than ImHex
