 # Build CMake with CMake.
 #   No ccmake needed.
 #   No cmake-gui needed.
+#   Static openssl is partially a problem:
+#       - Used by file(DOWNLOAD), etc: https://discourse.cmake.org/t/feature-request-curl-executable/1619/3
+#       - TLS verification will expect same paths on end-user machine as on build machine (so Alpine paths)
