[CMake] How to get target binary name?

[Christian Arnault]

Hi,

More generally speaking, I'm looking a way to query the existing 
configuration in terms of
- what are the libraries, executables, tests, etc...
- properties, compiler flags
declared through out various CMakeLists.txt
and WHERE they are declared ie in which directory (package)

This is also related with the former question: why to separate config 
phase from build phase?

In a very large project, made of a large number of packages in a wide 
DAG , developped by a large teas of developers, it's very desirable to 
QUERY such config without having to find/grep through out the zillions 
of CMakeLists.txt files.

It should trivial for CMake developers to add a kind of Database of all 
items to be constructed (basically all targets + how they are setup)

goals:

- debugging purposes
- understanding why/where/how a target exists
- understanding the relationships/dependencies between targets (even for 
those are not under your control)
- figure out the directory structure of the software base

I have managed to replace most of the add_xxx functions (plus some 
others) so as to offer the query feature to CMake but would it be 
offered by native CMake, this would be safer and efficient.

Comments?

Regards
Christian
