+# -G "Unix Makefiles". Change to -G "Ninja" if you want to build with ninja
+#
+# -DCMAKE_INSTALL_PREFIX=. -DCMAKE_INSTALL_LIBEXECDIR=libexec/
+# -DLIB_INSTALL_DIR=lib/ -DCMAKE_SKIP_RPATCH=ON - Required to have all the build
+# files and libs end up in your build/ directory so webkitfuzz uses those files
+# instead of the default on your machine
+#
+# -DENABLE_SANITIZERS=address - Build with ASAN
+# -DENABLE_MINIBROWSER=ON - webkitfuzz uses minibrowser
+#
+# The rest turn off dependencies not needed for most fuzzing cases
