 The build system supports a number of third-party dependencies
 
-  * ``BOOST``: for cross-platform support
-  * ``BROTLI``: for data compression
-  * ``Snappy``: for data compression
-  * ``gflags``: for command line utilities (formerly Googleflags)
-  * ``glog``: for logging
-  * ``Thrift``: Apache Thrift, for data serialization
-  * ``Protobuf``: Google Protocol Buffers, for data serialization
-  * ``GTEST``: Googletest, for testing
+  * ``AWSSDK``: for S3 support, requires system cURL even we use the
+    ``BUNDLE`` method described below

 The CMake option ``ARROW_DEPENDENCY_SOURCE`` is a global option that instructs
 the build system how to resolve each dependency. There are a few options:
