Adding dependencies to a setup project Win32 application Visual Studio - c++

Hi I am looking to create a setup project for my Win32 application developed using Visual Studio 2013. I have created the setup.exe using InstallShield However now i also need to add dependencies which should be installed along with the required application when setup.exe is run.
The dependencies are simply Visual C++ Redistributable for Visual Studio 2015.
I went through this article for creating the setup.exe for my application. But I did not find any documentation which directs me how to add dependencies to this installer.
I found this document which describes a walkthrough for adding dependencies but that is no more possible in Visual Studio 2013 as much as I am aware. Now we 'NEED' to use Install Shield. Correct me if I am wrong.
Please direct me to some documentation which will guide me to add dependencies to my setup project.
UPDATE
I found in the InstallShield Project Assistant an option to check for installation requirements. But it requires you to specify the directory to search the particular file. As far as I know the Visual C++ Redistributable package is not installed in any particular location but the only way to detect its presence is to check if the registry key is set to 1.
So instead of checking I'd rather always have the setup file to install the Visual C++ Redistributable package no matter it is present or no.
But even for that how do I go about it?

There might be other reasons you need to use InstallShield that I'm not aware of, but in the simple case of a C++ app that needs the runtime as a prerequisite, I'd use Visual Studio 2015 (Community Edition will do) and add the Installer project extension. The project properties lets you build a prerequisite installer (a setup.exe) and among the choices are the VC++ runtimes. That's just an exe that does its checks and installs if required.
I'm not sure how you got a VC 2015 C++ requirement while developing with VS 2013. Again, VS 2013 also has a community edition and an installer project extension that will install the VS 2013 C++ prerequisites.
The redistributable installers have their own checks to see if they need installing. I wouldn't expect InstallShield to require you to know the detection rules of a C++ runtime. that's a bit odd. There may be another setting where you just say C++ runtime required.

Visual Studio: copy installation folder and setup it up to be auto-detected by Qt Creator

I wiped out an old Windows 10 and replaced it with a new Windows 10 by ISO image.
Before wiping out, I copied the folder of Microsoft Visual Studio 2017 Community Edition on old Windows to an external hard disk:
xcopy /E "C:\Program Files (x86)\Microsoft Visual Studio" D:\
Now after reinstalling Windows 10, I copied the VS 2017 folder from external the hard disk to the C:\Program Files (x86)\ folder of new operating system.
I did so to avoid having to download VS 2017 again on new OS.
The problem is other software, like Qt Creator, cannot auto-detect the VS C/C++ compilers. I guess that's because the VS 2017 isn't added to path.
The questions are:
What path should I add to system path in order to VS 2017 to be auto-detected by other software like Qt Creator?
Is there any script which I can run to automatically integrate the VS 2017 to the rest of the operating system.
To answer the questions in your issue:
Copying the content of C:\Program Files (x86)\Microsoft Visual Studio folder is not a recommended way to install VS.
(The complete installation will not only set the Environment variables but also set the related registry keys and values. A simple copy may break this process)
So we always suggest that users install the VS by vs-installer or offline installation package. (Same like what Zlatomir suggests.)
To your actual requirements:
It seems you're just trying to use VC++ compiler in QT Creator instead of developing QT projects in Visual Studio. So build tools for VS package is enough for you.
See this related issue, if we download Build Tools for VS package with corresponding C++ workload, then we can get the compiler the QT needs. There's no need to install the VS IDE for this situation.
And if we need C++ compiler from VS2017, download the Build Tools for VS2017, if we need C++ compiler from VS2015, download the Build Tools for VS2015 Update3. Link of old version about VS Tools see here.
Update:
From the the link older downloads we can see:
Choose the download button according to which version we need. We can find both VS2017 build tools package and VS2015's there.
Usually programs on Windows don't work after you just copy the installation folder.
So right now there is little you can do to fix it, even if you partially fix, you have no way to know if something else will be broken in the future.
So the recommended solution is to download the installer again and create an offline installer for the next time this happens, you can do that by running the online installer with the following parameters: vs_community.exe --layout c:\vslayout --lang en-US (replace vs_community.exe with the actual name of the online installer file, or rename it), for more options, that might require a smaller download (example if you only need native and don't need .net) check the documentation here for the full set of options you have.

visual studio 2015. c++ console application converted in setup project with all dll

So i'm fairly new to VS and coding and I've recently made a small snake game in a C++ console application project, which works fine but i would like to get it to work on another PC without VS. The closest i have found to answering my question were these other StackOverflow questions here and here. i have installed the vs installer projects extension to try make it a setup project and include the required dependencies but i cant work out how to do this. Does anyone have any info to guide me through my last step of this problem or am i completely on the wrong track?
If the application uses dynamic runtime (which is the default), it uses the VS DLL files. To provide them, the Visual Studio Runtime Redistributable for that particular VS version needs to be installed on the target machine (as mentioned in your second link).
So that means you need to setup the installer that way. I didn't use it, but there might be some options that the resulting setup can either contain or download and install the VS redistributable automatically.
See also here: How to install redistributable with visual studio setup? (but it is for VS 2013, there might be some changes in 2015)
Well, you don't tell us what kind of project your C++ console app is...
Using only C++, your app can be built with different versions of the CRT, like for instance:
V120 (VS-2013)
V120_XP (VS-2013 w/ XP support)
V140 (VS-2015)
V140_XP (VS-2015 w/ XP support)
Even on VS 2015, you can choose the version of the CRT you want, and use an older version, if needed.
Anyway, the target computer will need the DLLs for the correct CRT version.
Microsoft provides them. You can either ship them with your product, if you have a custom installer, or use the installer provided by Microsoft.
MSDN - Determining Which DLLs to Redistribute
For instance, using V120:
msvcp120.dll
msvcr120.dll
Your project might also use .NET.
In such a case, you also need to install the correct version in the host machine.

how to get VS2013 c++ compiler to use with Qt without installing VS2013 [duplicate]

As per the title. I don't want to download the entire Visual C++ installer, only "cl.exe" and the other programs required for compiling and linking C++ programs on Windows.
As said, there is no way to do that. You need to download the entire 4-6GB+ bundle. MS deployment is a botch.
There is no need, however, to actually install everything. If you're up to some manual installation, you can extract individual components from the bundle and put them all in a more organized directory tree.
For example, I've found the following set to be the bare minimum needed for using the current MSVC2013 compilers in a x86 environment:
vc_compilerCore86.msi: MSVC toolchain;
vc_compilerCore86res.msi: MSVC toolchain MUI resources;
vc_librarycore86.msi: MSVC library stuff;
vc_LibraryDesktopX86.msi: More MSVC library stuff;
Windows Software Development Kit for Windows Store Apps-x86_en-us.msi: Windows SDK files and related tools (rc.exe, mt.exe, etc.);
Windows Software Development Kit-x86_en-us.msi: More Windows SDK files (specifically, WinSock2.h, WS2_32.lib, maybe others).
Remember that you can extract the contents of a MSI file by running msiexec /a <msifile> TARGETDIR="<path>" (jot a /quiet parameter if you're batching). Of course, you can also put more into your package by investigating the MSI files inside the bundle. In particular, the above set is missing the latest MSBuild tools, since I don't care for them. Stuff is often scattered around between multiple MSIs cluelessly, so good luck.
I've got a 50MB (!!!) 7z-file containing this set for local deployment, though I cannot share this publicly due to Microsoft licensing restrictions.

In 2014 you could not download the Visual C++ compiler alone from Microsoft.
It used to be that you could. Then it used to be that you could get it in the Platform SDK. Then you could only get it by installing Visual Studio.
Happily, at that time, the compiler that was bundled with Visual Studio Express for Desktop (the free version of Visual Studio at the time) was, and is, the very same that you get with Professional or Universal editions.

On March 21, 2022, the best I could figure out was to find the "Visual Studio Community" free download (required logging in with Microsoft account). There was no longer any "just give me the damn Build Tools" concept, but there is the promise that you just download an installer and then pick. So I downloaded the installer and ran it.
Of course, none of the top-level options are suitable for "just give me the damn Build Tools", so I pick the "Individual Components" option. This supplies an incredibly large list of things I don't want, but buried within it I find "MSVC v143 - VS 2022 C++ x64/x86 build tools (Latest)" which looks hopeful. I check that box and I'm informed they will give me also "Visual Studio code editor".
I'm sternly warned that I'm installing "without workloads", which seems to be some additional crap that the "Visual Studio core editor" I'm never going to use wants. I decline the additional bloatware. Some gigabytes later, it says I'm "Done installing" but warns "We recommend rebooting soon to clean up any remaining files."
After decades of (re-)writing scripts to locate the Microsoft compiler, I bow to Microsoft's superior ability to keep breaking any easy method of automating this process. Whenever I install the Microsoft compiler on a system, I manually set a system-wide environment variable that points to the Microsoft batch file for setting shell environment variables for the tools. Today's machine is a no-license (hey, Microsoft sucks the same way, just not as much!) Windows 10, and that is <Winkey>-x | System | Advanced System settings | Environment Variables
I create a variable called RLBVCVARS and set it to (in this particular case) c:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvarsall.bat My portable Windows dev environment keeps an alias that points to that so, I can mostly pretend Microsoft doesn't constantly introduce breaking changes to their installation schemes. I think you have to reboot for a "system" environment variable to take effect, but hey, Microsoft wants you to reboot after installing anything anyway, so no biggy.
First compile says can't find "io.h". Back to the installer. Let's try adding "Windows 10 SDK" (3 versions to choose from!). A GB or so later, I have an io.h and can build my current project. Onward and upward.

I create a variable called RLBVCVARS and set it to (in this particular case) c:\Program Files\Microsoft Visual Studio\2022\Community\VC\Auxiliary\Build\vcvarsall.bat My portable Windows dev environment keeps an alias that points to that so, I can mostly pretend Microsoft doesn't constantly introduce breaking changes to their installation schemes. I think you have to reboot for a "system" environment variable to take effect, but hey, Microsoft wants you to reboot after installing anything anyway, so no biggy.
First compile says can't find "io.h". Back to the installer. Let's try adding "Windows 10 SDK" (3 versions to choose from!). A GB or so later, I have an io.h and can build my current project. Onward and upward.

Is it possible to create WinRT project with cmake?

To create WINRT project we need to have CMake >= 2.8.10 and:
Set project type to be Windows Store App(CMAKE: SET_TARGET_PROPERTIES(target PROPERTIES VS_WINRT_EXTENSIONS TRUE)
Add compiler flag /ZW for WinRT compilation(CMAKE: ADD_DEFINITIONS(-ZW))
Add App.xaml.h, App.xaml.cpp
Add App.xaml so VS will generate some additional files from it(CMAKE: HOW?)
Add Package.appxmanifest with description so VS will use it(CMAKE: HOW?)
Thank you.
UPDATE: CMake bug report referring to this question is here 0013749: Cannot target Windows 8 RT from CMake without workarounds.
CMake guys are working on it:

This is perfectly doable. Things have considerably changed since this question was initially asked. The most significant changes are:
Visual Studio natively supports CMake since Visual Studio 2017 (see CMake support in Visual Studio). It's not longer required to separately download CMake, and have it generate .sln and .vcxproj files. CMake is part of the Visual Studio installation, and can be parsed by Visual Studio's project management infrastructure and build system.
C++/CX is no longer the only way to produce and consume Windows Runtime components. C++/WinRT provides a standard C++ language projection of the Windows Runtime API surface, with the ability to consume and produce Windows Runtime components.
With these changes you can use CMake to create a C++ project that builds a Windows Runtime application. C++/WinRT is standard C++, and Visual Studio 2017 provides built-in CMake support.
