I do use the ExternalProject to prebuild some binaries, without
the 'superproject' setup, and it does seem to work. Using the
add_dependencies, I can make sure some third party libs are
prebuild before I start to build my project. I have seen some
issues with ExternalProject (failing to extract, or build), but
they are too rare to pinpoint and create a bugreport.<br>
<br>
What exactly does not work? Is the external project not build at
all, or just not in time?<br>
<br>

<div>Hi.<br>
<br>
</div>
I've never worked with ExternalProject myself, so I can't
comment with certainty, but from what I understand, the
correct way of using ExternalProject is to add your own
project as an ExternalProject as well. Basically, the toplevel
CMakeList becomes a superbuild which *only* does
ExternalProject_Add() calls and does not add any
libraries/executables directly. After you build the superbuild
once to get all the dependencies correct, you switch to the
"external" project of your own code and work with that
normally.<br>
