在iOS项目中需要使用到curl库，由于版本更新，经常更新就需要重新找编译脚本，这里做下笔记： 首先需要使用到上篇Openssl 编译的通用文件。在通用文件下额外编译Curl库的脚本：
set -u
source ./build-ios-common.sh
if [ -z ${version+x} ]; then
version="7.68.0"
fi
TOOLS_ROOT=$(pwd)
SOURCE="$0"
while [ -h "$SOURCE" ]; do
DIR="$(cd -P "$(dirname "$SOURCE")" && pwd)"
SOURCE="$(readlink "$SOURCE")"
[[ $SOURCE != /* ]] && SOURCE="$DIR/$SOURCE"
done
pwd_path="$(cd -P "$(dirname "$SOURCE")" && pwd)"
echo pwd_path=${pwd_path}
echo TOOLS_ROOT=${TOOLS_ROOT}
LIB_VERSION="curl-$(echo $version | sed 's/\./_/g')"
LIB_NAME="curl-$version"
LIB_DEST_DIR="${pwd_path}/../output/ios/curl-universal"
init_log_color
echo "https://github.com/curl/curl/releases/download/${LIB_VERSION}/${LIB_NAME}.tar.gz"
# https://curl.haxx.se/download/${LIB_NAME}.tar.gz
# https://github.com/curl/curl/releases/download/curl-7_69_0/curl-7.69.0.tar.gz
# https://github.com/curl/curl/releases/download/curl-7_68_0/curl-7.68.0.tar.gz

同样如果直接使用通用脚本编译可能会报错，还是需要将：
-fembed-bitcode
删除，然后执行脚本就可以得到最新版本的Curl库。
注意：编译curl，暂时只支持gcc编译，虽然内部是调用clang，但是用clang编译，会报错：error "We can't compile without socket() support!"，如果知道答案，请指教。
