+Subject: [PATCH] Simplify finding the hip package
+
+On Fedora, where hip is installed as an rpm, its cmake files can
+not be found and are reported as an error.
+
+CMake Error at cmake/dependencies.cmake:44 (find_package):
+  No "FindHIP.cmake" found in CMAKE_MODULE_PATH.
+
+This change treats hip as a normal package.
