nested.
-For example:
+A common usage of generator expressions is to conditionally add compiler
+flags, such as those as language levels or warnings. A nice pattern is
+to associate this information to an ``INTERFACE`` target allowing this
+information to propagate. Lets start by constructing an ``INTERFACE``
+target and specifying the required C++ standard level of ``11`` instead
+of using ``CMAKE_CXX_STANDARD``.
-.. code-block:: cmake
+So the following code:
+
+.. literalinclude:: Step10/CMakeLists.txt
+ :language: cmake
+ :start-after: project(Tutorial)
+ :end-before: # Set the version number

+.. literalinclude:: Step11/CMakeLists.txt
+ :language: cmake
+ :start-after: project(Tutorial)
+ :end-before: # add compiler warning flags just when building this project via
+
+
+Next we add the desired compiler warning flags that we want for our
+project. As warning flags vary based on the compiler we use
+the ``COMPILE_LANG_AND_ID`` generator expression to control which
+flags to apply given a language and a set of compiler ids as seen
+below:
+
+.. literalinclude:: Step11/CMakeLists.txt
+ :language: cmake
+ :start-after: # the BUILD_INTERFACE genex
+ :end-before: # set the version number
+
+Looking at this we see that the warning flags are encapsulated inside a
+``BUILD_INTERFACE`` condition. This is done so that consumers of our installed
+project will not inherit our warning flags.
-.. code-block:: cmake
- target_compile_definitions(SqrtLibrary PRIVATE
- "$<$<BOOL:${HAVE_LOG}>:HAVE_LOG>"
- "$<$<BOOL:${HAVE_EXP}>:HAVE_EXP>"
- )
+**Exercise**: Modify ``MathFunctions/CMakeLists.txt`` so that
+all targets have a ``target_link_libraries()`` call to ``tutorial_compiler_flags``.
-Note that ``${HAVE_LOG}`` is evaluated at CMake configure time while
-``$<$<BOOL:${HAVE_LOG}>:HAVE_LOG>`` is evaluated at build system generation
-time.
