error: vcpkg not found!

错误不是很明显么，vcpkg 没找到，通过 xmake g --vcpkg=/xxx 或者 xmake f --vcpkg= 设置下

或者设置下 VCPKG_ROOT

另外，有 xmake-repo 自带 opencv 包干嘛不用，add_requires("opencv")

他这个不是现实我已经安装了，为什么还是失败 The following packages are already installed: opencv[core,default-features]:x64-windows-static -> 4.6.0

error: fetch vcpkg::opencv-latest failed!

fetch 包失败，装完没找到库文件，自己 https://github.com/xmake-io/xmake/blob/master/xmake/modules/package/manager/vcpkg/find_package.lua 里面加 print 调下。。

或者用 add_requires("opencv")

vcpkg是不是最好加一个cmake的find_package？vcpkg官方推荐也是从cmake引入，就是要手动设置opencv_ml opencv_dnn opencv_core opencv_flann 这些target稍微麻烦点

如果它的 info list 里面带了 cmake 文件，是可以通过 cmake find 来改进查找的，只是之前一直没空弄，还有 pacman 包也是目前仅支持从 pkgconfig找

waruqi avatar Sep 26 '22 23:09 waruqi

从 cmake 找不太好搞

这个包 info list 里面就这些

 /tmp/vcpkg/installed/vcpkg/info/opencv_4.6.0_x64-linux.list
x64-linux/
x64-linux/share/
x64-linux/share/opencv/
x64-linux/share/opencv/OpenCVConfig-version.cmake
x64-linux/share/opencv/OpenCVConfig.cmake
x64-linux/share/opencv/OpenCVModules-debug.cmake
x64-linux/share/opencv/OpenCVModules-release.cmake
x64-linux/share/opencv/OpenCVModules.cmake
x64-linux/share/opencv/vcpkg.spdx.json
x64-linux/share/opencv/vcpkg_abi_info.txt

直接找，缺 Protobuf，不知道在哪，感觉没 pkg-config 找起来方便可靠

$ CMAKE_PREFIX_PATH=/tmp/vcpkg/packages/opencv_x64-linux/share/opencv xmake l -vD find_package cmake::OpenCV

所以还不如直接用 xmake-repo 里面的 opencv

要用vcpkg的包需要加一个-DCMAKE_TOOLCHAIN_FILE=C:\vcpkg\scripts\buildsystems\vcpkg.cmake，不设置toolchain会有问题，只加一个config大概率不行

例如找不到protobuf，加了toolchain就可以找到vcpkg的其他依赖包

试了下，这样确实不报错了，但是没有 opencv 的 links

$ CMAKE_TOOLCHAIN_FILE=/tmp/vcpkg/scripts/buildsystems/vcpkg.cmake xmake l find_package cmake::OpenCV
{ 
  links = { 
    "dl",
    "m",
    "pthread",
    "rt" 
  },
  includedirs = { 
    "/tmp/vcpkg/installed/x64-linux/include" 
  } 
}

我看装完 opencv 有提示，还得额外手动配 link？

    # this is heuristically generated, and may not be correct
    find_package(OpenCV CONFIG REQUIRED)
    # note: 11 additional targets are not displayed.
    target_link_libraries(main PRIVATE opencv_ml opencv_dnn opencv_core opencv_flann)

waruqi avatar Oct 02 '22 00:10 waruqi

是的，要手动设置link

xq114 avatar Oct 02 '22 08:10 xq114

是的，要手动设置link

那就比较蛋疼了，这样，即使走 cmake 能找到，也没法自动 links 上，还得手动配各种 link
