print results/attempts for finding dependencies with cmake
Most dependencies are optional. In case they can not be found, the dependent parts of ACTS are disabled and a warning message is printed. To keep the configuration output short and comprehensive the cmake output from the attempt to find dependencies was silenced. However, it sometimes is desirably to install a certain dependency. In this case, the cmake output is actually very helpful to determine why a certain dependency could not be fulfilled. Thus, cmake output from finding external packages is enabled now by default. This behavior can be overwritten by specifying
-DACTS_FIND_QUIET=ON
during the cmake
command.
Closes ACTS-290.
