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.
