Populate extra_compile_args and extra_link_args as needed.

Regarding symlink(s) - resources:

Local-to-local symbolic link evaluation is: ENABLED
Local-to-remote symbolic link evaluation is: DISABLED

For puffer, config and resources don't have the above SYMLINKD status.

Trying git config core.symlinks true:

(as pufferl.py isn't in the execution path like environment.py is)

D:\puffer>

Python - pufferlib/ocean/target/target.py or elsewhere:

is_resource = not(os.path.exists("pufferlib"))
if is_resource:
    resource_path = "resources/..."
else:
    resource_path = "pufferlib/resources/..."

C - somewhere not per env: //TODO - file handling (eg. like this, but better)

May be raylib issue; LoadTexture using relative instead of absolute path - see pufferlib/ocean/environment.py.

Real problem is that resources is supposed to be a symlink to pufferlib/resources. PufferLib users should either enable symlink support on their device (sounds like if you have admin you can enable dev mode to make this work?) or replace the symlink with a directory junction to get this working. I don't think it makes sense to modify the code as a workaround (unless we're going to switch all resources to pufferlib/resources or a "base path" variable).

[KTibow]

Testing which changes are actually necessary:

• GitHub Workflows change is currently problematic (because most envs don't use msvc-style C)
• env_binding change seems out of scope and unneeded (I think)
• environment.py change is genuinely needed (bindings won't import correctly otherwise)
• pufferl.py change is genuinely needed (svmem only has active on unixlike)
• gitignore change seems out of scope and also oddly setup (raylib* already exists, so the # Raylib section is redundant)
• All setup.py changes aside from .replace('\\', '.') are genuinely needed

Perhaps 8bcc454; not necessarily out-of-scope - may be needed.
