I'm curious as to why you need the curl tool specifically. If you need to do something in curl within an OS X app, then you ought to use libcurl in your app instead of fork()/exec()-ing a curl process.

Anyway, if there's a good reason that you need the curl tool specifically, then you can do this (and this will work for any other tool you want to include in your app):

1. Install the latest command line tools on your computer, if you haven't done so already: xcode-select --install
2. Download the source code from <http://curl.haxx.se/>, un-pack it, and CD into its directory from the command line
3. Set the global environmental variable "MACOSX_DEPLOYMENT_TARGET" to "10.7" (or whatever your version requirement is; curl will go back as far as OS X 10.5)
4. Make a static build: ./configure --disable-shared --with-darwinssl --enable-threaded-resolver ; make -j `sysctl -n hw.logicalcpu_max`
(Note: OpenSSL is deprecated on OS X, but if you specifically need OpenSSL support for some reason, then omit the --with-darwinssl flag. And if you don't want TLS at all, then use --without-ssl.)
5. The tool will be located at ./src/curl after it's done building, so copy it into your project
6. You can then get the tool's path inside your app's bundle by using the CFBundle or NSBundle APIs
