Description

with conanfile.py require cpython

def requirements(self):
    self.requires("cpython/3.12.7")

then install

conan install . --build=missing -pr ../pr/msvc_debug -vv

but failed with

pywlauncher: The term 'pywlauncher' is not recognized as a name of a cmdlet, function, script file, or executable program.
Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

with -vv option, we see the full command

cpython/3.12.7: Full command: "C:\Users\jerry\.conan2\p\b\cpyth3ec40ffde3d92\b\build-debug\conan\conanbuild.bat" && pwsh -Command "&'C:\Users\jerry\.conan2\p\b\cpyth3ec40ffde3d92\b\build-debug\conan\conanbuild.ps1'" ; cmd /c "msbuild.exe \"C:\Users\jerry\.conan2\p\b\cpyth3ec40ffde3d92\b\src\PCbuild\pcbuild.sln\" -p:Configuration=\"Debug\" -p:Platform=x64 -target:venvwlauncher;pywlauncher;_tkinter;_multiprocessing;_msi;unicodedata;_queue;_bz2;_uuid;select;_asyncio;_zoneinfo;venvlauncher;_decimal;_overlapped;_lzma;_hashlib;_socket;_elementtree;_sqlite3;pyshellext;python3dll;_freeze_module;winsound;pythoncore;_wmi;_ctypes;pylauncher;python;pythonw;pyexpat;_ssl /p:PlatformToolset=v143"

In my opion, it seems that there is missing quoting in -target:xxxx of msbuild.exe,
i.e. It shoule be

msbuild.exe xxxx\b\src\PCbuild\pcbuild.sln `
  -p:Configuration=Debug -p:Platform=x64 `
  -target:"venvwlauncher;...;_ssl" /p:PlatformToolset=v143

note the quoting marks around venvwlauncher;...;_ssl.

You know, cmd quoting sucks.
