1. You have built SqlCipher to dynamically link with the OpenSSL library libeay32. This DLL needs to be available at run time for the plugin to be able to load.
2. Your configure command is a bit of a mess but probably not the cause of a failure to load. I would have expected something like:
Qt Code: 
  1. ./configure --disable-tcl \
  2.     CFLAGS="-DSQLITE_HAS_CODEC -DSQLCIPHER_CRYPTO_OPENSSL -I/c/openssl-win32/include" \
  3.     LDFLAGS="-L/c/openssl-win32/lib -leay32"
