+#### Incorporating Into An Existing CMake Project ####
+
+If you want to use gtest in a project which already uses CMake, then a
+more robust and flexible approach is to build gtest as part of that
+project directly. This is done by making the GoogleTest source code
+available to the main build and adding it using CMake's
+`add_subdirectory()` command. This has the significant advantage that
+the same compiler and linker settings are used between gtest and the
+rest of your project, so issues associated with using incompatible
+libraries (eg debug/release), etc. are avoided. This is particularly
+useful on Windows. Making GoogleTest's source code available to the
+main build can be done a few different ways:
+
+* Download the GoogleTest source code manually and place it at a
+  known location. This is the least flexible approach and can make
+  it more difficult to use with continuous integration systems, etc.
+* Embed the GoogleTest source code as a direct copy in the main
+  project's source tree. This is often the simplest approach, but is
+  also the hardest to keep up to date. Some organizations may not
+  permit this method.
+* Add GoogleTest as a git submodule or equivalent. This may not
+  always be possible or appropriate. Git submodules, for example,
+  have their own set of advantages and drawbacks.
+* Use CMake to download GoogleTest as part of the build's configure
+  step. This is just a little more complex, but doesn't have the
+  limitations of the other methods.
+
+The last of the above methods is implemented with a small piece
+of CMake code in a separate file (e.g. `CMakeLists.txt.in`) which
+is copied to the build area and then invoked as a sub-build
+_during the CMake stage_. That directory is then pulled into the
+main build with `add_subdirectory()`. For example:
+
+New file `CMakeLists.txt.in`:
