Executing workflow step 1 of 3: configure preset "default"

CMake Error at /usr/pkg/share/cmake-4.3/Modules/CMakeDetermineSystem.cmake:159 (message):

No, I didn' checkout the vcpkg repository. pkgsrc is a distribution,
so we'd like to provide the dependencies ourselves and not depend on
another distribution to provide them. (Also, I doubt vcpkg works on
NetBSD.)

Thanks.

Thanks.

Well, when packaging for pkgsrc we'd like to use the pkgsrc one.

CI for NetBSD is also available on github.
Here is a very simple example:
