According to Tetetest: # - lists of headers that 'configure' checks for; # - curl-specific tests (the ones that are in m4/curl-*.m4 files); # - (most obvious thing:) curl version numbers. # Add documentation subproject # # To check: # (From Daniel Stenberg) The cmake build selected to run gcc with -fPIC on my box while the plain configure script did not. # (From Daniel Stenberg) The gcc command line use neither -g nor any -O options. As a developer, I also treasure our configure scripts's --enable-debug option that sets a long range of "picky" compiler options. # 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/wolfSSL # HAVE_OPENSSL_SRP: `SSL_CTX_set_srp_username` present in OpenSSL/wolfSSL # HAVE_GNUTLS_SRP: `gnutls_srp_verifier` present in GnuTLS # HAVE_AWSLC: OpenSSL is AWS-LC # HAVE_BORINGSSL: OpenSSL is BoringSSL # HAVE_SSL_CTX_SET_QUIC_METHOD: `SSL_CTX_set_quic_method` present in OpenSSL/wolfSSL # HAVE_QUICHE_CONN_SET_QLOG_FD: `quiche_conn_set_qlog_fd` present in QUICHE # HAVE_ZSTD_CREATEDSTREAM: `ZSTD_createDStream` present in Zstd # # For each of the above variables, if the variable is DEFINED (either # to ON or OFF), the symbol detection will be skipped.
