To support 30# that case, additional variables may be defined by the parent 31# project, ideally in the "extra" find package redirect file: 32# https://cmake.org/cmake/help/latest/module/FetchContent.html#integrating-with-find-package 33# 34# The following variables are available: 35# HAVE_SSL_SET0_WBIO: `SSL_set0_wbio` present in OpenSSL/wolfSSL 36# HAVE_OPENSSL_SRP: `SSL_CTX_set_srp_username` present in OpenSSL/wolfSSL 37# HAVE_GNUTLS_SRP: `gnutls_srp_verifier` present in GnuTLS 38# HAVE_SSL_CTX_SET_QUIC_METHOD: `SSL_CTX_set_quic_method` present in OpenSSL/wolfSSL 39# HAVE_QUICHE_CONN_SET_QLOG_FD: `quiche_conn_set_qlog_fd` present in QUICHE 40# HAVE_ECH: ECH API checks for OpenSSL, BoringSSL or wolfSSL 41# 42# For each of the above variables, if the variable is DEFINED (either 43# to ON or OFF), the symbol detection will be skipped.
