@wep21 Hi! 😃 What is the purpose of this change?
Originally, glog was initialized in main(), so if this is changed to components, glog will not be initialized.

[wep21]

How about loading the ndt scan matcher component with glog component?
It is easier to change executor with component.

[wep21]

• Loading components may increase boot-up time.
• Main generated from template cannot initialize glog.
  So, I give up merging this PR
  @KYabuuchi Thank you for your comment.
