> <@bart:fam-ribbers.com> Actually, I'm not sure how to make the example find `glacierapp.h`, since the library isn't installed yet and it's not yet in `/usr/include/` 🤔

 * 1. Examples should link against Glacier::App
2. Glacier::App should (can?) expose CMAKE_CURRENT_SOURCE_DIR as a part of its BUILD_INTERFACE [1]
