Multi-level Directories

In the script field we can import various rich extension modules by import, and in the description field we can introduce the project subdirectory through the includes interface.

Remember: Xmake's includes handles the configuration relationship according to the tree structure. The target configuration in xmake.lua in the subdirectory inherits the root domain configuration in the parent xmake.lua, for example:

Currently, there is the following project structure:

Projectdir
    - xmake.lua
    - src
      - xmake.lua

projectdir/xmake.lua is the project's root xmake.lua configuration, and src/xmake.lua is a sub-configuration of the project.

projectdir/xmake.lua content:

add_defines("ROOT")

target("test1")
    set_kind("binary")
    add_files("src/*.c")
    add_defines("TEST1")

target("test2")
    set_kind("binary")
    add_files("src/*.c")
    add_defines("TEST2")

Includes("src")

The global root domain is configured with add_defines("ROOT"), which affects all target configurations below, including all target configurations in the sub-xmake.lua of includes, so this is the global total configuration.

The add_defines("TEST1") and add_defines("TEST2") in test1/test2 belong to the local configuration and only take effect on the current target.

src/xmake.lua content:

add_defines("ROOT2")

target("test3")
    set_kind("binary")
    add_files("src/*.c")
    add_defines("TEST3")

In the src/xmake.lua sub-configuration, there is also a global root domain, configured with add_defines("ROOT2"), which belongs to the sub-configuration root domain and only takes effect on all targets in the current sub-xmake.lua. For the target xmake.lua in the lower level includes the target, because as previously said, Xmake is the configuration inheritance relationship of the tree structure.

Therefore, the final configuration results of these targets are:

target("test1"): -DROOT -DTEST1
target("test2"): -DROOT -DTEST2
target("test3"): -DROOT -DROOT2 -DTEST3
