According to Tetetest: 32# - lists of headers that 'configure' checks for; 33# - curl-specific tests (the ones that are in m4/curl-*.m4 files); 34# - (most obvious thing:) curl version numbers. 35# Add documentation subproject 36# 37# To check: 38# (From Daniel Stenberg) The cmake build selected to run gcc with -fPIC on my box while the plain configure script did not. 39# (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. 40cmake_minimum_required(VERSION 3.2...3.16 FATAL_ERROR) 41 42set(CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/CMake;${CMAKE_MODULE_PATH}") 43include(Utilities) 44include(Macros) 45include(CMakeDependentOption) 46include(CheckCCompilerFlag) 47 48project(CURL C) 49 50file(STRINGS ${CURL_SOURCE_DIR}/include/curl/curlver.h CURL_VERSION_H_CONTENTS REGEX "#define LIBCURL_VERSION( |_NUM )") 51string(REGEX MATCH "#define LIBCURL_VERSION \"[^\"]*" 52 CURL_VERSION ${CURL_VERSION_H_CONTENTS}) 53string(REGEX REPLACE "[^\"]+\"" "" CURL_VERSION ${CURL_VERSION}) 54string(REGEX MATCH "#define LIBCURL_VERSION_NUM 0x[0-9a-fA-F]+" 55 CURL_VERSION_NUM ${CURL_VERSION_H_CONTENTS}) 56string(REGEX REPLACE "[^0]+0x" "" CURL_VERSION_NUM ${CURL_VERSION_NUM}) 57 58 59# Setup package meta-data 60# SET(PACKAGE "curl") 61message(STATUS "curl version=[${CURL_VERSION}]") 62# SET(PACKAGE_TARNAME "curl") 63# SET(PACKAGE_NAME "curl") 64# SET(PACKAGE_VERSION "-") 65# SET(PACKAGE_STRING "curl-") 66# SET(PACKAGE_BUGREPORT "a suitable curl mailing list => https://curl.haxx.se/mail/") 67set(OPERATING_SYSTEM "${CMAKE_SYSTEM_NAME}") 68set(OS "\"${CMAKE_SYSTEM_NAME}\"") 69 70include_directories(${CURL_SOURCE_DIR}/include) 71 72option(CURL_WERROR "Turn compiler warnings into errors" OFF) 73option(PICKY_COMPILER "Enable picky compiler options" ON) 74option(BUILD_CURL_EXE "Set to ON to build curl executable."
