Pointing cmake to libraries

[Hauke Fath <hf%spg.tu-darmstadt.de@localhost>]

Hi,

I have followed cmake down the rabbit hole...

A package (hiawatha) builds a set of shared libraries, and installs them 
at a custom path (${PREFIX}/lib/hiawatha). Unfortunately, the cmake 
build process does not provide the rpath to the binaries:

[...]
=> Checking for PIE in hiawatha-11.1
=> Checking for RELRO in hiawatha-11.1
=> Checking for missing run-time search paths in hiawatha-11.1

[...]

%  objdump -x 
/var/obj/pkgsrc/hauke/hiawatha/work/.destdir/usr/pkg/sbin/hiawatha | 
grep PATH
  RPATH                /usr/pkg/lib
%

I set various cmake variables, as suggested by the interwebs, to no 
avail. Autohell was byzantine, but at least grep(1)able. Sigh...

Any idea?

Cheerio,
Hauke
