No opencv_highgui module in OpenCV.sln solution file

[asic025]

Hi all,
I am using the Microsoft/opencv repository to develop projects with Raspberry PI 3 with Windows IoT installed (Visual Studio 2015 - Windows 10 on local machine and Raspberry - Windows IoT as remote machine).

I need to open and show images with cv::namedWindow() and cv::imshow(), but when I build my program (even running for test at the local machine : x86 architecture) I get "error LNK2019: unresolved external symbol" on namedWindow() and imshow().

Loading OpenCV.sln solution from the repository (i.e. for x86 architecture) I note that no opencv_highgui module is listed in Visual Studio Solution Explorer, and in fact, after build, no opencv_highgui300[d].dll and no opencv_highgui300[d].lib is produced in bin and lib directories.

How can I solve the problem?

Thank you in advance for the support.
