OK , I find how to make it works

• Install "MS Visual Studio" (community for example) and then install the "CMake tools"
• Start "MS Visual Studio" and search for the "Developper prompt", and start it. This "prompt" has the "path" of the tools in its environnement: Start this command prompt and type: "path" or "where cl.exe"
• This path could be add in the PC global setting to make it persistent: (In my case the path of "cl.exe" is "C:\Program Files\Microsoft Visual Studio\2022\Community\VC\Tools\MSVC\14.34.31933\bin\HostX86\x86"): Install this path the "environnement variables" in the system advanced property (SystemPropertiesAdvanced.exe)
