Comment:
I haven't used any of these IDEs to assess possible side-effects of only a launcher script for the GUI providing the required XXX_JDK var, compared to a global env var that can possibly be used by cli tools of those IDEs (shipping launcher scripts for them as well is overkill!).

To make IDE packages independent, I suggest each of them brings a file like this to /etc/profile.d
```
export XXX_JDK="$IDEA_JDK"
```
