[Bug 1170644] Re: link to c++ should be added to /usr/lib/ccache since cmake searches for it.

[Michał Sawicz]

Apparently it's the configure script for ccache that takes care of
creating the links, so `sudo dpkg-reconfigure ccache` should get it
going. Not sure yet why it doesn't create them initially - maybe if it's
installed before the compiler / alternative is built up?

Maybe it should have a dpkg trigger that would recreate the links based
on some criteria?

Title:
  link to c++ should be added to /usr/lib/ccache since cmake searches
  for it.

Status in “ccache” package in Ubuntu:
  Confirmed

Bug description:
  While using cmake in our project, we observed no ccache is used but
  ccache is installed correctly (and works with qmake for e.g.). cmake
  is using the c++ and will find it (/usr/bin) and therefore no ccache
  is used until we created a new link insicde /usr/local/ccache.

  This may also be cross related with the update-alternatives, which
  seems to provide the symlink.
