+            <p>Building on Mac OS X with Xcode is as easy as downloading the code and building the Xcode project or workspace:</p>
               <li><a href="download.html">Download</a> the lldb sources.</li>
               <li>Follow the code signing instructions in <b>lldb/docs/code-signing.txt</b></li>
               <li>In Xcode 3.x: <b>lldb/lldb.xcodeproj</b>, select the <b>lldb-tool</b> target, and build.</li>
               <li>In Xcode 4.x: <b>lldb/lldb.xcworkspace</b>, select the <b>lldb-tool</b> scheme, and build.</li>
+            <h2>Building LLDB with CMake</h2>
+            <p> First download the LLVM, Clang, and LLDB sources. Refer to <a href="source.html">this page</a> for precise instructions on this step.</p>
+            <p> Refer to the code signing instructions in <b>lldb/docs/code-signing.txt</b> for info on codesigning debugserver during the build.</p>
+            <p> Using CMake is documented on the <a href="http://llvm.org/docs/CMake.html">Building LLVM with CMake</a> page.
+            Ninja is the recommended generator to use when building LLDB with CMake.</p>
+            <code>
+              > cmake $PATH_TO_LLVM -G Ninja
+              <br />> ninja lldb
+            </code>
+            <p>
+               As noted in the "Building LLVM with CMake" page mentioned above, you can pass
+               variables to cmake to change build behavior. If LLDB is built as a part of LLVM,
+               then you can pass LLVM-specific CMake variables to cmake when building LLDB.
+            </p>
+            <p>Here are some commonly used LLDB-specific CMake variables:</p>
+            <ul>
+              <li><code><b>LLDB_EXPORT_ALL_SYMBOLS</b>:BOOL </code>: Exports all symbols. Useful in conjunction with CMAKE_BUILD_TYPE=Debug.</li>
+              <li><code><b>LLDB_BUILD_FRAMEWORK</b>:BOOL </code>: Builds LLDB.framework as Xcode would</li>
+              <li><code><b>LLDB_CODESIGN_IDENTITY</b>:STRING </code>: Skips building debugserver and therefore avoids codesigning anything.</li>
+            </ul>
