[cmake-developers] Extending CMAKE_EXPORT_COMPILE_COMMANDS

[Bertjan Broeksema]

Hi List,

I recently found out about the CMAKE_EXPORT_COMPILE_COMMANDS option while 
getting myself familiar with clang. In a tool [1] I'm working on (or rather, 
start to work again) I need something similar.

The current CMAKE_EXPORT_COMPILE_COMMANDS option only exports compile 
commands (as its name suggest). However, in my tool I build and visualize 
the full graph (i.e. source, headers, objectfiles, libaries). For this I 
also would need the link commands. Currently I've a wrapper around the C++ 
compiler, which works fine, but after having seen this option I realized 
that this would be way more convenient. Is it possible to get a similar 
option for exporting link commands or perhaps both:

CMAKE_EXPORT_LINK_COMMANDS
CMAKE_EXPORT_COMPILE_AND_LINK_COMMANDS

I'm willing to work on a patch, given that a) the option has a change to get 
included, b) I get some pointers on where to start to make it happen.

Cheers,

Bertjan
