支持强制包含

[jingkaimori]

你在什么场景下需要该功能？

墨干项目通过强制包含来引入配置文件，gcc 和 msvc 都支持强制包含选项，而且vscode的C++插件提供了强制包含的配置项。

• gcc: -include
• clang: -include
• msvc: /FI
• armcc: --preinclude, ARM® Compiler armcc User Guide, §8.154
• sdcc: -include, same as gcc, but needing further confirmation.
• tcc: not supported.

xmake 需要引入新的配置项，并且改进 msvc 插件，从而生成对应的强制包含信息

描述可能的解决方案

• [x] 定义域下为 target 添加set_forceinclude接口：
• [ ] vscode 插件根据上述接口修改c_cpp_properties.json文件

target("test")
    set_forceinclude({"src/config.h", "src/config_after.h"})

描述你认为的候选方案

目前的解决方案：

if is_plat("windows") then
    add_cxxflags("-FI " .. path.absolute("$(buildir)\\L1\\config.h"))
else
    add_cxxflags("-include $(buildir)/L1/config.h")
end

Title: supports mandatory inclusion

[waruqi]

加了 add_cincludes/add_cxxincludes，但不能指定路径，你只能配合 add_includedirs 来定位。。

add_cincludes("config.h")
add_includedirs("$(buildir)/L1")

xmake update -s github:xmake-io/xmake#includes

edit: 还有点问题，需要再改改

Added add_cincludes/add_cxxincludes, but you cannot specify the path, you can only locate it with add_includedirs. .

add_cincludes("config.h")
add_includedirs("src")

[waruqi]

改了下，再试试

add_forceincludes("config.h")
add_includedirs("$(buildir)/L1")

默认 add_forceincludes 匹配 c/c++/objc。如果仅仅只想匹配 c++ 可以

add_forceincludes("config.h", {sourcekinds = "cxx"})

如果想同时匹配多个源文件类型，可以

add_forceincludes("config.h", {sourcekinds = {"cxx", "mxx"}})

Change it and try again

add_force includes("config.h")
add_includedirs("$(buildir)/L1")

By default add_forceincludes matches c/c++/objc. If you only want to match c++ you can

add_force includes("config.h", {sourcekinds = "cxx"})

If you want to match multiple source file types at the same time, you can

add_force includes("config.h", {sourcekinds = {"cxx", "mxx"}})

现在能跑通了，add_forceincludes添加的各个文件出现在命令行的顺序能控制吗？

Now it works. Can the order in which the files added by add_forceincludes appear on the command line be controlled?

按添加的先后顺序，就跟 add_defines add_links 什么的类似。

According to the order of addition, it is similar to add_defines add_links or something.
