CentOS 7:
./configure -prefix=/opt/curl --enable-static=no --with-zlib=/opt/zlib LDFLAGS="-Wl,-rpath,'\$\$ORIGIN' $LDFLAGS"
gmake
gmake install

拷贝install路径下的lib目录下的动态库至platform下的对应系统目录
拷贝install路径下的include目录下的文件到ISCS_HOME/src/3rd/include目录

configure报告的信息如下：

[root@centos-7-5-test-2 bin]# ./curl -V
curl 7.61.1 (x86_64-pc-linux-gnu) libcurl/7.61.1 OpenSSL/1.0.2k zlib/1.2.7

Windows：

详见源码包winbuild目录下的说明

复制zlib的头文件zconf.h、zlib.h到E:\src_package\zlib_install_debug\include
复制zlib的编译后库文件到E:\src_package\zlib_install_debug\lib

nmake /f Makefile.vc WITH_DEVEL=E:\src_package\zlib_install_debug WITH_ZLIB=dll mode=dll VC=14 MACHINE=x64 DEBUG=yes

若希望Debug、Release版本统一文件名，即Debug版本不带“_debug”，则修改MakefileBuild.vc文件
BASE_NAME_DEBUG、BASE_NAME_STATIC_DEBUG去掉“_debug”

release同理。
nmake /f Makefile.vc WITH_DEVEL=E:\src_package\zlib_install_release WITH_ZLIB=dll mode=dll VC=14 MACHINE=x64 DEBUG=no

支持信息如下：
E:\src_package\curl-7.61.1\builds\libcurl-vc14-x64-debug-dll-zlib-dll-ipv6-sspi-winssl\bin>curl.exe -V
