perhaps something as simple like this would do already?

LIBSSH2_API
uint32_t libssh2_buildinfo()
{
     uint32_t buildinfo = 0;
#if defined(LIBSSH2_WINDOWSCRYPT) /* build with Windows native Crypt API */
     buildinfo |= 0x00000004;
#elif defined(LIBSSH2_LIBGCRYPT) /* build with libgcrypt */
     buildinfo |= 0x00000002;
#else /* must be build with OpenSSL */
     buildinfo |= 0x00000001;
#endif
#if defined(LIBSSH2_HAVE_ZLIB) /* build with Zlib support */
     buildinfo |= 0x00010000;
#endif
     return buildinfo;
}

GŁn.
