+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
+patch was rejected by upstream and later reverted in Debian. Thus those two
+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
+negatives just blacklist those two versions.
