 ### Setting up your project with CMake
 
-You need to set the path to prioritize our custom CMake, and also to see our MSVC installation.
+You need to add the our MSVC installation to the path.
 After that we just run CMake command with a few extra settings:
 
 ```bash
-export PATH=~/my_msvc/opt/cmake/bin:$PATH
 export PATH=~/my_msvc/opt/msvc/bin/x64:$PATH

 ## Does it work with CMake?
 
-Yes, but a custom version is needed or else CMake will complain that `/opt/msvc/bin/x64/cl` can't build a simple program.
-
-It also fixes the `Ninja` Generator which otherwise has trouble finding RC.
+Yes, but you need CMake 3.23, and either need `winbind` installed, or
+need to configure the build to always use embedded debug info (or a
+custom build of CMake that doesn't try to use separate PDB file debug
+info by default).
+
+Even if configuring CMake with `-DCMAKE_BUILD_TYPE=Release`, CMake does
+call the compiler in `Debug` mode when it does the first few test
+invocations of the compiler. By default, CMake uses separate PDB
+file debug info, when compiling in `Debug` mode, i.e. using the
+`/Zi` compiler option (as opposed to the `/Z7` option, storing the
+debug info in the individual object files).
+
+When MSVC is invoked with the `/Zi` option, it spawns a background
+`mspdbsrv.exe` process and communicates with it. This requires
+the `winbind` package to be installed for this communication to work.
+
+With CMake 3.25, it's possible to override the type of debug info
+even for the first few probing steps. This requires the CMake project
+to either set `cmake_minimum_required(VERSION 3.25.0)`, or set
+`cmake_policy(SET CMP0141 NEW)`, and requires the user to configure it
+with `-DCMAKE_MSVC_DEBUG_INFORMATION_FORMAT=Embedded`; in such a
+configuration, `winbind` isn't needed.
