[Bug]: MSB3101 build error when trying to build project after adding new source file due to permissions error

[brno32]

Detailed steps on how to reproduce the bug

• start a new project (I used this template https://github.com/TheAudioProgrammer/JuceAudioPluginTemplate)
• run cmake -B build -G "Visual Studio 17 2022", open the .sln file (as a regular user, NOT as an admin), hit build. so far so good
• add a new C++ class. I added Square.h and Square.cpp. the content doesn't matter
• call out these files in CMakeLists.txt
• run CMake again, then try to build, and observe the error MSB3101
• reopen Visual Studio as an administrator
• build again and it works

What is the expected behaviour?

that command should return exit code 0 and the project should build

Operating systems

Windows

What versions of the operating systems?

Windows 11

Hey!

Visual Studio has a tendency to regenerate the solution during a build. It should regenerate the solution when you save the CMake file after making changes, but it often doesn't.

You can manually trigger a regeneration by right-clicking on the CMakeLists.txt in the "Solution Explorer" and selecting "Compile" (this only regenerates the solution, it doesn't actually build anything).

Alternatively, opening the project as a folder (File -> Open -> Folder) often handles CMake changes more reliably, so I'd recommend trying that approach.

If neither works, could you paste the full CMake or Build output from the Output window after a failed build?
