</div>one thing I had trouble with is related to the install step.<br>
<br>
With externalProject the install step happens at build time.<br>
If shared libraries are involved, the install destination should be the<br>
correct and final install destination, so that the RPATH of using projects<br>
will point to the correct location.<br>
This means that at build time I need to have the permissions to write to the<br>
final install destination (e.g. /opt/), i.e. typically root.<br>
<br>
Is this correct or am I missing something ?<br>
<br>
