[CMake] What is the best way to handle Boost dependencies in a package config file

[Johnson, Matt (GE Healthcare)]

I like package config files.  I want to use more of them.  However, I have a dependency on boost.  While boost has a Find module, it doesn't have a package config file.  I'm not going to be able to depend on the users of my package building boost via cmake (also, is that still an active thing?).

It seems like the best I could hope for is to generate the package config file, then hack it up to deal with the boost stuff.  Has anyone already solved this problem or have any tips?  I found this Hunter package manager (https://github.com/ruslo/hunter), but it seems a bit heavyweight when all I want is boost.  Also, I can't have my build system going out and downloading the packages - they all have to come from an internal source.  

Thanks,
Matt
