# Note: By default this CMake build script detects the version of some
# dependencies using `check_symbol_exists`. Those checks do not work in
# the case that both CURL and its dependency are included as sub-projects
# in a larger build using `FetchContent`. To support that case, additional
# variables may be defined by the parent project, ideally in the "extra"
# find package redirect file:
# https://cmake.org/cmake/help/latest/module/FetchContent.html#integrating-with-find-package
#
# The following variables are available:
# HAVE_SSL_SET0_WBIO: `SSL_set0_wbio` present in OpenSSL
# HAVE_OPENSSL_SRP: `SSL_CTX_set_srp_username` present in OpenSSL
# HAVE_GNUTLS_SRP: `gnutls_srp_verifier` present in GnuTLS
# HAVE_SSL_SET_QUIC_USE_LEGACY_CODEPOINT: `SSL_set_quic_use_legacy_codepoint` present in OpenSSL/wolfSSL
# HAVE_QUICHE_CONN_SET_QLOG_FD: `quiche_conn_set_qlog_fd` present in quiche
# HAVE_ECH: ECH API checks for OpenSSL, BoringSSL or wolfSSL
#
# For each of the above variables, if the variable is DEFINED (either
# to ON or OFF), the symbol detection is skipped. If the variable is
# NOT DEFINED, the symbol detection is performed.
