Did you follow the instructions in the error message?

@edenhill
hi, the nuget already download zlib, The error still exists.

[edenhill]

How are you performing the NuGet restore, through Visual studio solutions menu or command line?

@edenhill
hi, thanks for your reply. i use the Visual studio solutions menu, can you release a vs2017 .sln file?

The issue is that librdkafka.vcxproj has elements such as:

<Import Project="packages\zlib.$(PlatformToolset).windesktop.msvcstl.dyn.rt-dyn.1.2.8.8\build\native\zlib.$(PlatformToolset).windesktop.msvcstl.dyn.rt-dyn.targets" Condition="Exists('packages\zlib.$(PlatformToolset).windesktop.msvcstl.dyn.rt-dyn.1.2.8.8\build\native\zlib.$(PlatformToolset).windesktop.msvcstl.dyn.rt-dyn.targets')" />

whereas $(PlatformToolset) resolves to v141 and the Nuget packages that are restored in packages.config are v140.
I hacked out the librdkafka.vcxproj and changed zlib.$(PlatformToolset) to zlib.v140

@ElasticCoder Hi,thanks for your reply,I modified the librdkafka.vcxproj and changed all "zlib.$(PlatformToolset)" to "zlib.v140",but cause build failed with can't find zlib.h(fatal error C1083: 无法打开包括文件: “zlib.h”: No such file or directory),it seems the project doesn't include zlib header path. I also found the "$(Force-Disable-zlib-v140-windesktop-msvcstl-dyn-rt-dyn)" macro in this project setting was set to true,maybe lead to no zlib was imported.Can I set this macro to false or just remove it manually?

while using VS2017 with default toolset as v141 , modify the toolset of libkafka.vcxproj to v140 ( VS 2015) , it shud build
