1) There are three items with same number "1.":

• Create a directory to hold the programs. This example will call it "AMQ7C++SmokeTest", but you can use any name you like.
• Enter the new directory.
• Copy all the examples to this directory.

I think it could be 1., 2. and 3.
-----------------------------------------
2) After command

$ cp -r /usr/share/proton-0.16.0/examples/cpp .

the user will not be able to run next commands

cmake .

and

make

because copy command copied whole directory, not only files.

Two options:
a) add command

cd cpp

between this two parts

b) change copy command to

$ cp -r /usr/share/proton-0.16.0/examples/cpp/* .
