detecting vs2015 comes with vs2019 properly

[lygstate]

According to C:\Program Files (x86)\Microsoft Visual Studio\2019\Community\VC\Auxiliary\Build\vcvarsall.bat We can specify options for vs2015 or vs 2017

:usage_error
echo [ERROR:%~nx0] Error in script usage. The correct usage is:
goto :usage

:usage
echo Syntax:
echo     %~nx0 [arch] [platform_type] [winsdk_version] [-vcvars_ver=vc_version] [-vcvars_spectre_libs=spectre_mode]
echo where :
echo     [arch]: x86 ^| amd64 ^| x86_amd64 ^| x86_arm ^| x86_arm64 ^| amd64_x86 ^| amd64_arm ^| amd64_arm64
echo     [platform_type]: {empty} ^| store ^| uwp
echo     [winsdk_version] : full Windows 10 SDK number (e.g. 10.0.10240.0) or "8.1" to use the Windows 8.1 SDK.
echo     [vc_version] : {none} for latest installed VC++ compiler toolset ^|
echo                    "14.0" for VC++ 2015 Compiler Toolset ^|
echo                    "14.xx" for the latest 14.xx.yyyyy toolset installed (e.g. "14.11") ^|
echo                    "14.xx.yyyyy" for a specific full version number (e.g. "14.11.25503")
echo     [spectre_mode] : {none} for libraries without spectre mitigations ^|
echo                      "spectre" for libraries with spectre mitigations
echo:
echo The store parameter sets environment variables to support Universal Windows Platform application
echo development and is an alias for 'uwp'.
echo:
echo For example:
echo     %~nx0 x86_amd64
echo     %~nx0 x86_amd64 10.0.10240.0
echo     %~nx0 x86_arm uwp 10.0.10240.0
echo     %~nx0 x86_arm onecore 10.0.10240.0 -vcvars_ver=14.0
echo     %~nx0 x64 8.1
echo     %~nx0 x64 store 8.1
echo:
echo Please make sure either Visual Studio or C++ Build SKU is installed.
goto :end

:missing
echo The specified configuration type is missing.  The tools for the
echo configuration might not be installed.
goto :end

:end

So we can detecting vs2015 proplery

Thank you for the idea, I was not aware of this user scenario for the vcvars script. We may not be able to implement this immediately but we will monitor the community reactions (please give a thumbs up on the first entry of this GitHub issue) to find how this best fits in our backlog.

[andreeis]

@lygstate, I just tried -vcvars_ver=14.0 for a VS 2019 vcvarsall.bat and it points to a VS 14.0 installation (as opposed to some different toolset with the same version but placed within the VS 2019 location). And that VS 14.0 is detected already as a kit by this extension. Please give us a few more details about what is not working now, how do you run vcvars, what toolset is using and from where, is it not present in cmake-tools-kits.json already?

Yeap, that's what I want, currently the vscode cmake tools didn't detect vs2015 by using -vcvars_ver=14.0 when vs 2019 installed. And detecting directly with "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\vcvarsall.bat" will fail building when the newest windows sdk are installed(The rc.exe can not found).

[andreeis]

Just to confirm, you are opening VSCode from a terminal where you didn't run vcvars yourself, right? You know that the extension does this when needed: run the appropriate vcvars script, from the correct location, with the correct arguments.... well ideally, there can always be bugs about that.

So you have both VS 2019 and VS 2015 installed and you don't see any VS 2015 kits detected when scanning for kits? And before (before installing latest sdk if I understand correctly) VS 2015 was found by the kits scan? I haven't seen this, VS 2015 is properly detected where I tried this. I'll brainstorm more about why this can happen and I'll see what else I can try to reproduce this.

What's a "cmake.loggingLevel": "Debug" logging in the "CMake/Build" output channel after scanning for kits?

This is used to resolve the following issue: The vs2015 installed with vs2019 can not be used, because using newest SDK along with vs vs2019
