   1 # cURL/libcurl CMake script
   2 # by Tetetest and Sukender (Benoit Neil)
   3
   4 # TODO:
   5 # The output .so file lacks the soname number which we currently have within the lib/Makefile.am file
   6 # Add full (4 or 5 libs) SSL support
   7 # 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).
   8 # Add CTests(?)
   9 # Check on all possible platforms
  10 # Test with as many configurations possible (With or without any option)
  11 # Create scripts that help keeping the CMake build system up to date (to reduce maintenance). According to Tetetest:
  12 #  - lists of headers that 'configure' checks for;
  13 #  - curl-specific tests (the ones that are in m4/curl-*.m4 files);
  14 #  - (most obvious thing:) curl version numbers.
  15 # Add documentation subproject
  16 #
  17 # To check:
  18 # (From Daniel Stenberg) The cmake build selected to run gcc with -fPIC on my box while the plain configure script did not.
  19 # (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.
