With the INSTALL instructions in <qpid>/cpp the "Building from a Source
Distribution" instructions are fairly near the bottom.
I kind of see the logic of that since the earlier sections are describing prerequisites, but I wonder if it's worth moving the main install bit closer to the top with a line that says something like "If you have not installed qpid previously see prerequisites below".
Similarly section "2.2.2. From Source" might be better in the prerequisites section rather than the install section, I think that's particularly worthwhile now because 2.2.2 is talking about an automake build for
the dependencies and the qpid install is now cmake. I know that I did a double take when I skimmed through and assumed that the instructions hadn't been updated for cmake until I read again.
