trigger CMAKE_SYSTEM_NAME STREQUAL "WindowsStore"

[foxnight2]

I build the libdatachannel on windows and show the variable "CMAKE_SYSTEM_NAME".
The "CMAKE_SYSTEM_NAME " is Windows.

How can I trigger the WindowsStore?

Does it just do -DCMAKE_SYSTEM_NAME=WindowsStore ?
If you are on windows, you will not do -DCMAKE_SYSTEM_NAME=Linux.
The system will automatically detect the Windows.

You can't have CMake automatically guessing that you want to target Windows Store on Windows, so you need to pass -DCMAKE_SYSTEM_NAME=WindowsStore.

In the future, please ask CMake questions unrelated to libdatachannel like this one on a CMake forum instead of here, or refer directly to the CMake documentation.
