How to install gsl 2.6 by using vcpkg?

I am using vcpkg to install gsl on Windows. The gsl-version being installed is:

Source: gsl
Version: 2.4-5
Homepage: https://www.gnu.org/software/gsl/

However, I need the functionalities of the latest version of gsl, i.e. 2.6.

Is there any possiblity to install gsl 2.6 by using vcpkg?

Solution

You can use

vcpkg.exe x-history gsl

to see git commit ids which change the CONTROL file of the GSL port which can be used to checkout a specific version of GSL. The result for GSL is:

as you can see 2.6 is not part of that history but I added a PR to update the gsl port to 2.6 (see https://github.com/microsoft/vcpkg/pull/10758)

Feel free to merge that PR into your local clone of vcpkg or use the vcpkg --port-overlay feature. As soon as the PR is merged you can just vcpkg.exe install gsl to get the updated version.
