The most reasonable way to achieve this goal would be to write scripts<br>
that replace the configure/build/install steps of the projects that<br>
you want to isolate with DESTDIR.<br>
<br>
Then, inside the script (which will only be executed at build time of<br>
the outer project), use set(ENV{DESTDIR} "...") to set it<br>
appropriately just for that project.<br>
<br>
Unfortunately, CMake's add_custom_command does not yet have a<br>
mechanism for specifying environment variables just for a single<br>
custom command.<br>
<br>
So, for now, the best work-around is to write scripts as needed.<br>
