Interesting. This would do for Ninja what the IMPLICIT_DEPENDS option does for Makefile generators.

Since the behavior is specific to Ninja perhaps it should be called NINJA_DEPFILE.

Here is a command which would benefit from this: https://gitlab.kitware.com/vtk/vtk/merge_requests/56 [^]

Ah, if it would be Ninja-specific, then yes. May as well support NINJA_DEPFORMAT if someone wants to write MSVC-style dependency info as well for some reason (or someone had another format coded up *whistles*).

Hi,

I found this feature request while looking for Ninja + IMPLICIT_DEPENDS.

I have projects with code generation steps, in some cases from C/C++ files (for which I can use IMPLICIT_DEPENDS), in others from XML (for which there is no way to generate dependencies at build time).

The kind of feature requested here would help me a lot, but it should not be restricted to one generator, rather it should use a generic format that all generators can convert to their specific formats.

I use CMake because it's portable I a would prefer not to write configuration files with switches that depend on the generator used (already the fact that IMPLICIT_DEPENDS only work for Makefile is very annoying).

Cheers
Marco
