+
+#. After CMake has finished running, proceed to use IDE project files, or start
+ the build from the build directory:
+
+ .. code-block:: console
+
+ $ cmake --build .
+
+ The ``--build`` option tells ``cmake`` to invoke the underlying build
+ tool (``make``, ``ninja``, ``xcodebuild``, ``msbuild``, etc.)
+
+ The underlying build tool can be invoked directly, of course, but
+ the ``--build`` option is portable.
+
+#. After LLVM has finished building, install it from the build directory:
+
+ .. code-block:: console
+
+ $ cmake --build . --target install
+
+ The ``--target`` option with ``install`` parameter in addition to
+ the ``--build`` option tells ``cmake`` to build the ``install`` target.
+
+ It is possible to set a different install prefix at installation time
+ by invoking the ``cmake_install.cmake`` script generated in the
+ build directory:
+
+ .. code-block:: console
+
+ $ cmake -DCMAKE_INSTALL_PREFIX=/tmp/llvm -P cmake_install.cmake
