T4 template files are automatically recognizable by the IDE under C# projects, but I have no clue on how they can be integrated into C++ projects (other than using make files).
Any ideas?
T4 Template files can be integrated into C++ projects, but it's a bit more work than with a C#/VB project. Create a new text file in your C++ project and give it a .tt extension. Then write your template as normal. A C++ project then needs further work to get it to transform the templates. The quick and dirty way I got it to work was to add a custom build step and have it call "C:\Program Files\Common Files\Microsoft Shared\TextTemplating\1.1\TextTransform.exe" directly. Another way I found was to add a custom MSBuild task. Instructions can be found here
This page has more information and some good links to other pages on using T4 code generation.
MSBuild Task will not work as this is a vcproj file (C++) so vcbuild is used. The easiest way to get the tt compiled is to add a custom build step like below..
"C:\Program Files (x86)\Common Files\Microsoft Shared\TextTemplating\1.1\TextTransform.exe" -out "$(ProjectDir)\VSProject.cpp" -I "$(ProjectDir)" "$(ProjectDir)\VSProject.tt"
I spent several hours investigating the MSBuild Task solution above and it's pretty good for managed code but I can't see any way to use it for C++ (bar converting the vcproj to csproj eek)
For Visual Studio 2017 (and maybe 2015?)
The commands listed in the other answers are partly incorrect, as the file TextTransform.exe has been moved to a new directory: the devenv root folder, e.g.:
C:\Progra~1\Visual Studio 2017\Enterprise\Common7\IDE
The command should now be updated to the following:
"$(DevEnvDir)TextTransform.exe" -out "$(ProjectDir)xxx.cpp" "$(ProjectDir)xxx.tt"
where xxx is the file name of yout .tt template file
