Hi Alexander, <br><br>Assuming the subproject are CMakeified:<br><br> 1) Set the INSTALL command of each External project to an empty string<br> 2 ) In yout CPack file, you could use a syntax similar to the one reported below:<br>
<font size="1"><br style="font-family: courier new,monospace;"><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">if(EXISTS "${VTK_DIR}/CMakeCache.txt")</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;"> set(CPACK_INSTALL_CMAKE_PROJECTS "${CPACK_INSTALL_CMAKE_PROJECTS};${VTK_DIR};VTK;RuntimeLibraries;/")</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">endif()</span><br style="font-family: courier new,monospace;">
<br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;">if(EXISTS "${ITK_DIR}/CMakeCache.txt")</span><br style="font-family: courier new,monospace;"><span style="font-family: courier new,monospace;"> set(CPACK_INSTALL_CMAKE_PROJECTS "${CPACK_INSTALL_CMAKE_PROJECTS};${ITK_DIR};ITK;RuntimeLibraries;/")</span><br style="font-family: courier new,monospace;">
<span style="font-family: courier new,monospace;">endif()<br><br><br></span></font><br><div class="gmail_quote">For more details: <a href="http://viewvc.slicer.org/viewvc.cgi/Slicer4/trunk/SlicerCPack.cmake?revision=16507&view=markup">http://viewvc.slicer.org/viewvc.cgi/Slicer4/trunk/SlicerCPack.cmake?revision=16507&view=markup</a><br>

Hi,<br>
<br>
I'd like to set up a kind of meta super project, which builds a bunch of<br>
subprojects, which contains executable and shared libraries.<br>
These subprojects come from different repositories, mostly git repositories.<br>
<br>
AFAIK I can basically do this using the ExternalProject_add() feature of<br>
cmake, it will get the sources, configure and build them.<br>
<br>
So far so good.<br>
<br>
<br>
Now, what do I do with installing ?<br>
Usually the external projects are installed at the end of their build step at<br>
make-time, and usually somewhere in the build tree.<br>
<br>
But finally I'd like to have these projects installed into a proper system-<br>
wide directory.<br>
<br>
If I simply do install(DIRECTORY ... ) in the "superproject", stuff which<br>
depends on CMAKE_INSTALL_PREFIX, like e.g. RPATH will be wrong after the final<br>
install step (since the RPATHs will still point to the install locations in<br>
the build tree).<br>
<br>
If I put the final install location as install location in the<br>
ExternalProject_Add() call, I will have to build with permissions to install<br>
into the final install directory, which is generally not the case. E.g. to<br>
install in /opt/ I would basically have to build as root (or change the<br>
permissions of /opt/, but that's not possible on a standard system).<br>
<br>
I could maybe also setuid cmake root (ugly too).<br>
<br>
Always set a relative RPATH always using $ORIGIN ?<br>
(but this will be kind of hard to enforce)<br>
<br>
Any other ideas ?<br>
Am I missing something ?<br>
Any ideas how support for this could be added in a clean way ?<br>
<br>
Alex<br>
