<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
There are two concepts: CMAKE_INSTALL_PREFIX and DESTDIR, that I think you need to apply now.</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
<br>
</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
As a refresher, here is my understanding. CMAKE_INSTALL_PREFIX must be set to the directory, where the artifacts should reside in the custom os. That is most probably "/usr". That should set the the RPATH correctly.<br>
</div>
<br>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
However, from packaging point of view, this causes a little trouble. Because when someone calls make install, the artifacts will be installed to CMAKE_INSTALL_PREFIX, merging the new files with the build OS files. And from that it is very hard to collect the
artifacts properly.</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
<br>
</div>
<div style="font-family:Calibri,Arial,Helvetica,sans-serif;font-size:12pt;color:rgb(0,0,0)">
That is what DESTDIR is intended to resolve. Instead of calling make install, one needs to call make DESTDIR=<abs path to artifact directory> install. That will create the same structure that would have been created in CMAKE_INSTALL_PREFIX, just in $DESTDIR/$CMAKE_INSTALL_PREFIX.
From that you can call targz or anything on the directory to collect the artifacts.</div>
