Right. Debian doesn't want this either.

Some of what I've wanted to do in "make install" to help with this:

  * Figure out the right way to run "ldconfig" from "make install"

  * Test if the runtime linker will be able to find the library, and if
not print a message about setting LD_LIBRARY_PATH (or
DYLD_LIBRARY_PATH).

Setting rpath with the option to prevent this might be possible too. But
we can't do this unconditionally.

Hello Chris,

I know that many distros (among them Fedora, see
https://fedoraproject.org/wiki/Packaging/Guidelines#Beware_of_Rpath )
discourage the use of rpath. Do you think it could be an option set at
configure time (set rpath or not) ?

[PATCH] Makefile: specify libnotmuch.so location with -rpath

In order to handle installation into user directories, it is convenient
to encode the library location into the search path for the notmuch
executable. This is achieved for the GNU linker with the -rpath
argument.
