描述

In the colord project we have a lib/colord/foo.h and internally .c files are allowed to either the single file (e.g. if the library itself is building) #include "cd-foo.h" or #include <colord/colord.h>. To support this I tried:

in lib/meson.build:

lib_incdir = include_directories('.')

in lib/colord/meson.build:

colord_incdir = []
colord_incdir += include_directories('.')
colord_incdir += lib_incdir

and then in the various places (e.g. src/meson.build) we have to pass the include_directories:

include_directories : [
  colord_incdir,
],

This fails to configure with:

Meson encountered an error in file src/meson.build, line 26, column 0:
Include directory to be added is not an include directory object.

Ideas?

研究方向
The issue involves combining multiple include directories objects. The error 'Include directory to be added is not an include directory object' suggests a type check failure. The contributor should start by searching for 'include directories' in the Meson source code, likely in `mesonbuild/interpreterbase.py` or `mesonbuild/compilers/mixins/gnu.py`. Reproduce the issue with a minimal Meson project, trace the error, and identify where the type validation occurs. Then propose a fix to allow proper handling of include directory objects in lists.
