+Subject: [PATCH] CMake: Avoid reordering CMAKE_CXX_FLAGS
+
+Order matters; the reordering caused the _FORTIFY_SOURCE flag to be
+always undefined (as we flipped a "-U" and "-D")
+
+Also skip removing duplicates to avoid similar pitfalls (we kept
+only the first occurrence but should've kept the last)
+It did not work properly anyway (we still had duplicates in the end)
+and was only required as we wrote the final CMAKE_CXX_FLAGS back to
+cache and consequently appended new flags with every run of CMAKE.
