How do I package up a set of CMake functions to be distributed via VCPKG?

[Cazadorro]

I have a set of convenience CMake functions and variables that I'd like to use across several different projects. Right now I'm forced to manually copy each file or use a git submodule to use them. I could fetch content, but my understanding is that anything like that breaks --only-download and other offline usages of VCPKG, since those cmake commands wouldn't be run until package build time (which is too late to fetch things from the internet). I would like to instead see if I could use VCPKG to do this, I see

https://github.com/microsoft/vcpkg/tree/cb1e4728779e35c4bb60c25114a59c93b3e9be9a/ports/vcpkg-cmake-config

vcpkg-cmake-config and friends are basically what this is (though I'm not sure I can access these anywhere but inside of a portfile?). You add things like vcpkg-cmake-config to get access to certain cmake functions inside of the portfie.cmake. I would basically like to be able to do that, but * actually use my own functions in a CMakeLists.txt* that is utilize vcpkg packages, and hopefully as if they were normal cmake files to include (ie include(my-cmake-function-file.cmake)).

Is there a method to accomplish this?

Provide your functions as a CMake config package.

• Let's assume your port is called my-scripts.
• Let the port install your script functions as share/my-scripts/my-scripts-config.cmake.
• In your CMake projects, simply do find_package(my-scripts CONFIG REQUIRED)

And this basically works even without vcpkg - just offer the config file in a location searched by find_package.
