+If a library does not offer configure options to select the build variant, the build must be patched. When patching a build, you should always attempt to maximize the future maintainability of the port. Typically this means minimizing the number of lines that need to be touched to fix the issue at hand.
+
+#### Example: Patching a CMake library to avoid building unwanted variants
+
+For example, when patching a CMake-based library, it may be sufficient to add [`EXCLUDE_FROM_ALL`](https://cmake.org/cmake/help/latest/prop_tgt/EXCLUDE_FROM_ALL.html) to unwanted targets and wrap the `install(TARGETS ...)` call in an `if(BUILD_SHARED_LIBS)`. This will be shorter than wrapping or deleting every line that mentions the unwanted variant.
+
+For a project `CMakeLists.txt` with the following contents:
+```cmake
+add_library(contoso SHARED contoso.c)
+add_library(contoso_static STATIC contoso.c)
+
+install(TARGETS contoso contoso_static EXPORT ContosoTargets)
+
+install(EXPORT ContosoTargets
+  FILE ContosoTargets
+  NAMESPACE contoso::
+  DESTINATION share/contoso)
+```
+
+Only the `install(TARGETS)` line needs to be patched.
+```cmake
+add_library(contoso SHARED contoso.c)
+add_library(contoso_static STATIC contoso.c)
+
+if(BUILD_SHARED_LIBS)
+  set_target_properties(contoso_static PROPERTIES EXCLUDE_FROM_ALL 1)

+else()

+endif()

 ### When defining features, explicitly control dependencies
 
 When defining a feature that captures an optional dependency, ensure that the dependency will not be used accidentally when the feature is not explicitly enabled.

-When making changes to a library, strive to minimize the final diff. This means you should _not_ reformat the upstream source code when making changes that affect a region. Also, when disabling a conditional, it is better to add a `AND FALSE` or `&& 0` to the condition than to delete every line of the conditional.

When disabling a conditional, it is better to add an `AND FALSE` or `&& 0` to the condition than to delete every line of the conditional. If a large region needs to be disabled, it is shorter to add an `if(0)` or `#if 0` around the region instead of deleting every line in the patch.

 This helps to keep the size of the vcpkg repository down as well as improves the likelihood that the patch will apply to future code versions.
