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. cmake_minimum_required(VERSION 3.0 FATAL_ERROR) set(CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/CMake;${CMAKE_MODULE_PATH}") include(Utilities) include(Macros) include(CMakeDependentOption) include(CheckCCompilerFlag) project(CURL C) message(WARNING "the curl cmake build system is poorly maintained.
