Yes, but there is a separate list in each cmMakefile for each source
directory. You'd have to traverse the entire structure to find all
of them.

They are created by install() command invocations. See the impl in
`Source/cmInstallCommand.cxx`. For each target the artifacts are
each given an install generator. Then there is a block that adds
all of them:
```
this->Makefile->AddInstallGenerator(archiveGenerator);
this->Makefile->AddInstallGenerator(libraryGenerator);
this->Makefile->AddInstallGenerator(runtimeGenerator);
...
```
The code model reported by your protocol needs to cover the possibility
of more than one install(TARGETS) command for a given target. Each
target may be installed to zero or more destinations. You could either
try to put this in a list inside each target, or separately model our
concept of installation lists that reference targets instead.
