I've demoed this to Argyrios Kyrtzidis ~year ago and he was impressed by it's 
parsing speed :-)
NB needed just 1 minute to parse whole LLVM+Clang 3.4 codebase on my laptop.
Also I was complaining that migrating to i.e. Clang's preprocessor makes us 2x 
slower (which is still the case for upcoming NB 8.1, but we trying to restore 
our speed)

NetBeans for a long time has own "build interceptor". It helps to put code bases 
with even really complex build systems into IDE.
When developer uses Project with Existing Sources wizard and specify commands 
which he proceed in cmd shell, then IDE executes them and interpose compiler 
invocations to extract cwd and all flags passed to compiler.
Then all is persisted in project properties, so user gain "Compile File" for 
free, because IDE for each file knows how it was compiled.
For CMake based codebases json database is produced and used to extract flags.
Am I answering your question? Or do you mean smth different?
