+    FindLIBOPENJPEG2.cmake: Remove cache code
+
+    It wasn't working since the if mentioned LIBOPENJPEG2_INCLUDE_DIR
+    instead of LIBOPENJPEG2_INCLUDE_DIRS
+    and when fixing the typo it broke the build because we were not
+    defining USE_OPENJPEG2, so better just
+    remove the broken if code
