@end smallexample

@majorheading Description

Searches for the 'gcrypt' library with the --with... option.

If found, define HAVE_GCRYPT and macro GCRYPT_LIBS and GCRYPT_CFLAGS.
Also defines GCRYPT_WITH_<algo> for the algorithms found available.
Possible algorithms are: AES ARCFOUR BLOWFISH CAST5 DES IDEA RFC2268
SERPENT TWOFISH CRC HAVAL MD2 MD4 MD5 RMD160 SHA0 SHA1 SHA224 SHA256
SHA384 SHA512 TIGER WHIRLPOOL DSA ELGAMAL RSA

The argument is used if no --with...-gcrypt option is set. Value "yes"
requires the configuration by default. Value "no" does not require it by
default. Value "auto" configures the library only if available.
