Well, there's a lot in the KDE community, but when starting out with
cmake for a large project, it really might help to take a look at
extra-cmake-modules first (https://api.kde.org/ecm/) because it contains
a lot of useful stuff, and then at just one large KDE project, like my
own, Krita. Krita actually contains two cmake systems: one to build Krita
(which consists of several executables, a bunch of libraries and a host
of plugins), and one to download and build all dependencies using cmake
external projects. 

I'm sure it can and should be improved and modernized, but it's at
least an example :-)
