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.
