+By default CMake ignores CPPFLAGS thus missing those hardening flags. Debian
+patched CMake in versions 2.8.7-1 and 2.8.7-2 to respect CPPFLAGS, but this

+versions show correct usage of CPPFLAGS even if the package doesn't correctly
+handle them (for example by passing them to CFLAGS). To prevent false
