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