I apologize for not following closely earlier... once packages have
been installed, what happens, if anything, to package-relative paths
and the code that uses them? The installed layout would look
something like (still flexible):
/opt/
ros/
<xturtle>/
include/
lib/
bin/
etc/
share/
<package1>/
cmake/
resources/
(stuff)
<package2>/
cmake/
resources/
....
Who needs to know whether we are installed or not? Where would the manifest go?
