In fact, this is all that I really needed to change in CMakeLists.txt:
--- CMakeLists.txt (revision 1859)
+++ CMakeLists.txt (working copy)
@@ -499,6 +506,7 @@
${LIBCRYPTO_LDFLAGS}
${LIBCRYPTO_LIBRARIES}
${LIBJPEG_LIBRARIES}
+ ${OPENSSL_LIBRARIES}
${PLATFORM_SYSTEM_LIBRARIES}
${stlport_libraries_if_use_stlport}
${FREETYPE_LIBRARIES}
