Looks like nmake.exe not found. Try to fix this problem first. I recommend to use "Developer Command Prompt for VS 2019" to build when Toolchain is set to VS2019. You could type below command to check if your command prompt could run it without errors. > > nmake.exe /? > Regards, Adam -=-=-=-=-=-=-=-=-=-=-=- Groups.io Links: You receive all messages sent to this group.
