Comment (by alamaison):
The important thing with ExternalProject is that you can't just use it in
your project's CMakeLists.txt because it doesn't fetch and build the
subprojects until main project build time - too late for find_package,
which runs at configure time, to pick them up. You have to make a wrapper
project that uses ExternalProject to build the dependencies and also uses
ExternalProject to build your project. This setup is called a CMake
Superbuild or superproject.
Hunter avoids the need for a superbuild but building the dependency
projects at main project configure time.
Thanks for the patch. I'll try and test it tonight
