  25. # Note: By default this CMake build script detects the version of some
  26. # dependencies using `check_symbol_exists`. Those checks do not work
  27. # in the case that both CURL and its dependency are included as
  28. # sub-projects in a larger build using `FetchContent`. To support
  29. # that case, additional variables may be defined by the parent
  30. # project, ideally in the "extra" find package redirect file:
  31. # https://cmake.org/cmake/help/latest/module/FetchContent.html#integrating-with-find-package

  33. # The following variables are available:
  34. # HAVE_SSL_SET0_WBIO: `SSL_set0_wbio` present in OpenSSL/wolfSSL
  35. # HAVE_OPENSSL_SRP: `SSL_CTX_set_srp_username` present in OpenSSL/wolfSSL
  36. # HAVE_GNUTLS_SRP: `gnutls_srp_verifier` present in GnuTLS

  41. # For each of the above variables, if the variable is DEFINED (either
