  24. # curl/libcurl CMake script
  25. # by Tetetest and Sukender (Benoit Neil)
  26. # TODO:
  27. # The output .so file lacks the soname number which we currently have within the lib/Makefile.am file
  28. # Add full (4 or 5 libs) SSL support
  29. # Add INSTALL target (EXTRA_DIST variables in Makefile.am may be moved to Makefile.inc so that CMake/CPack is aware of what's to include).
  30. # Check on all possible platforms
  31. # Test with as many configurations possible (With or without any option)
  32. # Create scripts that help keeping the CMake build system up to date (to reduce maintenance). According to Tetetest:
  33. # - lists of headers that 'configure' checks for;
  34. # - curl-specific tests (the ones that are in m4/curl-*.m4 files);
  35. # - (most obvious thing:) curl version numbers.
  36. # Add documentation subproject
  37. #
  38. # To check:
  39. # (From Daniel Stenberg) The cmake build selected to run gcc with -fPIC on my box while the plain configure script did not.
  40. # (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.
  41. # Note: By default this CMake build script detects the version of some
  42. # dependencies using `check_symbol_exists`. Those checks do not work
  43. # in the case that both CURL and its dependency are included as
  44. # sub-projects in a larger build using `FetchContent`. To support
  45. # that case, additional variables may be defined by the parent
  46. # project, ideally in the "extra" find package redirect file:
  47. # https://cmake.org/cmake/help/latest/module/FetchContent.html#integrating-with-find-package
  48. #
  49. # The following variables are available:
  50. # HAVE_RAND_EGD: `RAND_egd` present in OpenSSL
  51. # HAVE_BORINGSSL: OpenSSL is BoringSSL
  52. # HAVE_PK11_CREATEMANAGEDGENERICOBJECTL: `PK11_CreateManagedGenericObject` present in NSS
  53. # HAVE_SSL_CTX_SET_QUIC_METHOD: `SSL_CTX_set_quic_method` present in OpenSSL
  54. # HAVE_QUICHE_CONN_SET_QLOG_FD: `quiche_conn_set_qlog_fd` present in QUICHE
  55. # HAVE_ZSTD_CREATEDSTREAM: `ZSTD_createDStream` present in Zstd
  56. #
  57. # For each of the above variables, if the variable is DEFINED (either
  58. # to ON or OFF), the symbol detection will be skipped. If the
  59. # variable is NOT DEFINED, the symbol detection will be performed.
