+Subject: [PATCH] CMake: Allow using BUILD_SHARED_LIBS to choose static/shared
+ libs
+
+By convention projects using CMake which can build either static or
+shared libraries use a BUILD_SHARED_LIBS flag to allow selecting between
+both: the add_library() command automatically switches between both using
+this variable when the library kind is not passed to add_library(). It
+is also usual to expose the BUILD_SHARED_LIBS as an user-facing setting
+with the option() command.
+
+This way, the following will both work as expected:
+
+   % cmake -DBUILD_SHARED_LIBS=OFF ...
+   % cmake -DBUILS_SHARED_LIBS=ON ...
+
+This is helpful for distributions which need (or want) to build only
+static libraries.
