Unable to populate OpenCppCoverage Settings dialog

[claremacrae]

Background

The info from About Visual Studio dialog is below...

I have a small program open - a tiny Catch2 test - and OpenCppCoveragePlugin installed...

The build config is x64-Debug
I can run and debug the program.

Problem

When I select Tools -> OpenCppCoverage Settings the dialog looks like this - and none of the widgets respond to clicks...

The Command Line tab says:

--config_file "C:\Users\clare\AppData\Local\Temp\n3moeomh.gc3"
--

Question

How do I get my project's properties to be loaded in to this dialog please?

I used OpenCppCoveragePlugin a year ago, and have dim memories have to create a settings.json-type file, but cannot find any references to that in the docs now.

Any advice gratefully received... Thank you.

Check if it works better to use the context menu of the exe you want to test. The tools menu entry is for the currently selected startup project, it seems. Each project has its own setup which is stored somewhere and is not destroyed when cmake recreates the vcxproj files luckily.
