Building Azure IoT Gateway SDK Solution with CMake Utility - azure

Question

I'm trying to build a sample Azure IoT Gateway SDK project with CMake 3.71 utility for Visual Studio 2015 on Windows 10 platform. When I tried to build the project both in VS2015 Command Line and CMake GUI, respectively, I got the following error log:
Determining if the _M_AMD64 exist failed with the following output:

Output from the CMake GUI here
Can someone tell me what I'm doing wrong or guide me? I have spent significant amount of hours trying to figure out how to solve the issue. I have extensively searched for solutions online, but to no success.
Thanks in advance

Answer 1

It seems to be related with this note:
Note: Make sure to clone the repo into a directory heirachy with less
than 20 characters (if the path is prefix\azure-iot-gateway-sdk,
prefix must be less than 20 characters). Windows has limitations on
the length of file names and placing the repo in a hierarchy deeper
than 20 characters will cause the build to fail. Our build.cmd script
throws an error if it would eventually hit this failure, but one can
hit this when manually building the project with cmake.
I kill the "project" in the directory(...Documents/GitHub/project/azure-iot-gateway-sdk/...), then it works.
So, you need shorten the length of the directory that you clone the repo into.
