22 # curl/libcurl CMake script
23 # by Tetetest and Sukender (Benoit Neil)
24
25 # TODO:
26 # The output .so file lacks the soname number which we currently have within the lib/Makefile.am file
27 # Add full (4 or 5 libs) SSL support
28 # 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).
29 # Add CTests(?)
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.
