An existing build system for your SDL app has good chances

An existing build system for your SDL app has good chances to work almost

|
|||
a barebones .app bundle, which is double-clickable from the Finder. But
|
||||
there are some more things you should do before shipping your product...
|
||||
|
||||
1. The bundle right now probably is dynamically linked against SDL. That
|
||||
means that when you copy it to another computer, *it will not run*,
|
||||
unless you also install SDL on that other computer. A good solution
|
||||
for this dilemma is to static link against SDL. On macOS, you can
|
||||
achieve that by linking against the libraries listed by
|
||||
|
||||
```bash
|
||||
sdl3-config --static-libs
|
||||
```
|
||||
|
||||
instead of those listed by
|
||||
|
||||
```bash
|
||||
sdl3-config --libs
|
||||
```
|
||||
|
||||
Depending on how exactly SDL is integrated into your build systems, the
|
||||
way to achieve that varies, so I won't describe it here in detail
|
||||
1. You'll need to copy the SDL framework into the Contents/Frameworks
|
||||
folder in your bundle, so it is included along with your application.
|
||||
|
||||
2. Add an 'Info.plist' to your application. That is a special XML file which
|
||||
contains some meta-information about your application (like some copyright
