Old visual studio generators in recent cmake

Hi,
I use cmake with conan to generate prebuild version of libraries for different Visual Studio version and architecture.

We mostly use Visual Studio 2022 and 2019, but we still need to support new library version (bug fixes) for Visual Studio 2013 and 2008.

Unfortunately, I just discover that cmake version 3.31 drops support for Visual Studio 2013 generator and the support for Visual Studio 2008 was dropped too in a previous version.

Beside, installing an older cmake version, how can I get back these generators?
Can I extract them from older version an place somewhere in my cmake forlder?

The main problem is that often people/developers have to rebuild a library in their laptops because they need a specific version with specific option that is not available in our repository and I’m sure that most of them have a cmake version that does not support anymore these generators.

I read I can use for instance the generator for VS 2015 setting vc120 as toolchain but this mean that I have to install another visual studio version and I’m not sure if conan is happy to have a library version for VS2013 build with another version of the compiler.

Thanks

With VS 2022 installer, you may install the older toolchains too until VS2015 AFAIK
