Title: opencv: Use vcpkg::opencv under win. vcpkg has been successfully installed, but xmake cannot check.

add_packages 要跟 add_requires 的包名一致 add_packages("vcpkg::opencv[contrib,freetype]")，否则关联不上。。如果你 add_packages 不想写这么长，那就设置 alias

add_requires("vcpkg::opencv[contrib,freetype]", {alias = "opencv"})

add_requires("vcpkg::opencv[contrib,freetype]", {alias = "opencv"})

他这里好像都没有到 add_packages的阶段，还在install的时候就寄了

waruqi commented 1 month ago

那就自己调下这里，https://github.com/xmake-io/xmake/blob/dev/xmake/modules/package/manager/vcpkg/find_package.lua

fetch 没找到安装后的包而已。

Then adjust it here yourself, https://github.com/xmake-io/xmake/blob/dev/xmake/modules/package/manager/vcpkg/find_package.lua

fetch did not find the installed package.

刚尝试调试了一下，发现xmake读取这个 infofile里的内容，但是里面只有这些内容，并没有 include，lib等文件夹。不知道是不是新版的vcpkg做了改动

opencv_4.8.0_x64-windows-static.list 里面没有 opencv4_4.8.0_x64-windows-static.list 这个里面倒是有 include，lib这些

Issues-translate-bot commented 1 month ago

There is no opencv_4.8.0_x64-windows-static.list opencv4_4.8.0_x64-windows-static.list contains include, lib, etc.

waruqi commented 1 month ago

那这种目前解析不了，先得确认库和头文件路径在哪。啥也没有就没办法了。。

所以建议用 xmake-repo 的 opencv 包

Issues-translate-bot commented 1 month ago

This kind of problem cannot be parsed at present. You must first confirm where the library and header file paths are. If there is nothing, there is nothing we can do. .

Therefore, it is recommended to use the opencv package of xmake-repo

嗯，我改成 add_requires("vcpkg::opencv4[contrib,freetype]", {alias = "opencv"})，动态库倒是可以用，静态库好像是没有级联依赖导致报一堆像libpng之类的其他依赖库未定义的错误

目前 vcpkg/conan 的级联依赖需要一个个声明，动态库自然都包含进去，而静态库需要手动链接

waruqi commented 1 month ago

只有 xmake-repo 仓库的包才支持级联依赖。。三方包不支持

Only packages in the xmake-repo warehouse support cascading dependencies. . Third-party packages are not supported

xmake-io / xmake-repo
