Passing command line arguments to Visual Studio using CMake for profile guided optimization

Question

I'm using CMake for a C++ project. I'm trying to use profile guided optimization so I need to also pass command line arguments to the Release mode version of my binary. Visual Studio needs this to create a performance profile. I already have a launch.vs.json configuration for the Debug mode binary with command line arguments:

{
  "version": "0.2.1",
  "defaults": {},
  "configurations": [
    {
      "name": "MyProject",
      "project": "CMakeLists.txt",
      "projectTarget": "MyProject.exe",
      "type": "default",
      "args": [
        "...", "..."
      ]
    }
  ]
}

When I switch to Release mode and choose the MyProject startup item, Visual Studio shows the following error message:

Unable to start debugging. The startup project could not be launched.

Why does it not work that way? I also cannot setup another profile and make Visual Studio recognize it in Release mode but it works fine in Debug mode.

Probably need to add more context, like your configuration. Could be anything. — Matthieu Brucher, Dec 11 '18 at 15:07

I managed to do it now by adding another entry:

{
  "version": "0.2.1",
  "defaults": {},
  "configurations": [
    {
      "name": "MyProject",
      "project": "CMakeLists.txt",
      "projectTarget": "MyProject.exe",
      "type": "default",
      "args": ["...", "..."]
    },
    {
      "name": "MyProject (Release\\MyProject.exe)",
      "project": "CMakeLists.txt",
      "projectTarget": "MyProject.exe (Release\\MyProject.exe)",
      "type": "default",
      "args": ["...", "..."]
    }
  ]
}
