cmake opencv debug库与release库链接问题

[Ligo04]

add_requires("cmake::OpenCV",{alias = "opencv",system=true,configs = {
        envs = {CMAKE_BUILD_TYPE="Release"}，debug=false
}})
add_packages("opencv")

用cmake查找包时，如何区分链接到debug库和release库，像下面debug和release都同时连接到

我想知道如何去掉debug版本的依赖

[waruqi]

你调下这里

xmake/xmake/modules/package/manager/vcpkg/find_package.lua

Line 122 in 683c5ce

if line:find(triplet .. (mode == "debug" and "/debug" or "") .. "/lib/", 1, true) then

[Ligo04]

貌似没有调用到vpckg的find_package，而是cmake的find_packaga

[waruqi]

cmake 的包啊，那就没事了，cmake 吐啥就获取啥，你自己 扩展参数配，让它只吐 release 库，如果没参数控制，那我也没办法，你得找 cmake 和这个cmake项目那边反馈。。

可配置参数，文档里看下。。https://xmake.io/#/zh-cn/package/local_package?id=find-packages-from-cmake

xmake 这边也只是内部调用 cmake 的 find_package 去获取，它给什么过来，就获取什么

这原本就非常依赖每个 cmake 包的配置，不可靠，且复杂，除非必要，建议不要这么搞，直接用 xmake-repo 仓库包

[Ligo04]

好吧，可配置参数我基本都试过了。。。 我一开始用xrepo 安装opencv 出现了问题，然后试试用cmake包，然后发现了debug和release的依赖都附加进去了，我看源码貌似读vcxproj配置，并没有区分release和debug

cmake 的包，在 xmake 层面是区分不出 debug/release 的，不同 cmake 库区分 debug/release 的配置原本就有差异。cmake find_package 吐什么就获取什么

你看下上面的文档，可以传 cmake 库自身的一些配置进去，到 configs/presets 如何控制到它 find_package 返回的结果，那就能区分，如果没配置能控制，那就没办法，只能到 cmake 库那边项目提 issues/pr 去改进导出的 .cmake files

[Ligo04]

嗯，我还是用回xrepo先了，感谢作者大大的回答
