Similar issue was posted here a while ago. These are two different things:

1) I am deleting some binaries which were at some point incorrectly installed in the wrong place (cadabra-qt5 and related). These, I agree, should go (that issue will most likely not bite anyone anymore).

2) Icons. I have been battling icons for days, and there simply seems to be no universally working solution that makes icons show up if you install them in anything but /usr/share/icons. Please tell me I am wrong about that and I'll happily change that part of the installation.

Even if /usr/share/icons is the only reasonable path for icons, it is not a good idea to ignore DESTDIR.

[kpeeters]

That doesn't solve my problem; either I install in /usr/share/icons or I don't install at all. What do you suggest when DESTDIR != /usr ?

[suhr]

DESTDIR is not PREFIX. It is the staging dir. From the docs:

If your installation step would normally install /usr/local/bin/foo and /usr/local/lib/libfoo.a, then an installation invoked as in the example above would install /tmp/stage/usr/local/bin/foo and /tmp/stage/usr/local/lib/libfoo.a instead.

You can ignore the prefix and install into /tmp/stage/usr/share/icons instead of /tmp/stage/usr/local/share/icons. But you should not ignore the DESTDIR, it is commonly used by package managers.

d11e42b67ee59fd5e6688ce18d5516e08cfc08f0 should fix this; let me know if it doesn't.
