多个子工程通过环境变量或者 option 控制导入

[davidxiaozhi]

你在什么场景下需要该功能？

多个子工程通过环境变量或者 option 控制导入,例如 GPu 和 CPU 下导入的工程的数量是不一样的,GPU key 包含 CPU, 但是 CPU 模式仅仅只有 CPU

描述可能的解决方案

例如
// cpu 模式或 gpu 模式
includes("cpu/")
includes("cpu_test/")
//only GPU 模式
includes("gpu/")

描述你认为的候选方案

例如
// cpu 模式或 gpu 模式
includes("cpu/")
includes("cpu_test/")
//only GPU 模式
includes("gpu/")

Title: Multiple subprojects are imported through environment variables or options

In what scenario do you need this function?

Multiple sub-projects are imported through environment variables or options. For example, the number of projects imported under GPU and CPU is different. GPU key includes CPU, but CPU mode only has CPU

describe possible solutions

For example
// cpu mode or gpu mode
includes("cpu/")
includes("cpu_test/")
//only GPU mode
includes("gpu/")

Describe what you think is a candidate

For example
// cpu mode or gpu mode
includes("cpu/")
includes("cpu_test/")
//only GPU mode
includes("gpu/")

@waruqi 如何在 xmake.lua 当中依据一个 option 或者环境变量的配置动态includes()
相对于
if ("$(device)"=="gpu") then
includes("cpu")
includes("gpu")
elseif ("$(device)"=="gcu") then
includes("cpu")
includes("gcu")
else
includes("cpu")
end

[waruqi]

if is_config("device", "gpu") then
    includes("cpu", "gpu")
end
