Do not use FeatureSummary to report found packages
The use of feature_summary in GaudiDependencies.cmake
is a bad idea as it produces a lot of noise in downstream projects (see #181 (closed)).
This MR drops it to use the normal REQUIRED
flag of find_package
.
A better approach is to use find_dependency
in GaudiConfig.cmake
(see #205), but for the moment this is enough.
Closes #181 (closed)
