+        [CMake] Use builtin FindICU
+        https://bugs.webkit.org/show_bug.cgi?id=197934
+
+        Reviewed by Michael Catanzaro.
+
+        Update CMake minimum required to 3.7. 3.7 has a FindICU module so the WebKit one
+        is removed. For non-Apple ports this just requires adding individual components of
+        ICU to find_package(ICU). For Apple ports the module does not work so the targets
+        created in FindICU are mirrored in target/icu.cmake.
+
+        * CMakeLists.txt:
+        * Source/cmake/FindICU.cmake: Removed.
