Are you sure you installed Conan? https://conan.io/downloads.html

Are you sure you installed Conan? https://conan.io/downloads.html

Conan is fetched from https://github.com/conan-io/conan/releases/download/1.24.0/conan-win-64_1_24_0.exe, and

$ conan --version
Conan version 1.24.0

this is because some conan related urls are blocked by GFW, try using a proxy. Conan urls are basicly inaccessable from China for unknown reason

How to setup? I tried ssr, but same problem.

I also opened the SSR, and added a proxy to conan's configuration file(USER.conanconan.conf), but it still does not work.

Besides，I found a solution on stackoverflow( https://stackoverflow.com/questions/62024613/cmake-errors-using-conan-in-the-yuzu-generator )
The CMakeLists.txt of the yuzu repository (found at the parent directory) requires version 1.24.0 of conan, while the latest is 1.25.2. I assume you have installed the latest version. Change line 252 from: conan_check(VERSION 1.24.0 REQUIRED) to: conan_check(VERSION 1.25.2 REQUIRED)
But it also does not work.

@spacejumpunreal is right, thanks a lot.
After I used a VPN via SS, the compilation finally succeeded. I recommend you may try to choose a VPS.

Did you compile successfully with VPN？But I can't.

1. I also opened the SSR, and added a proxy to conan's configuration file(user_dir.conanconan.conf), but it still does not work.
2. I found a solution on stackoverflow( https://stackoverflow.com/questions/62024613/cmake-errors-using-conan-in-the-yuzu-generator ), he said that maybe the conan's version in CMakeLists.txt was wrong, and I changed it to the local conan's version, but it still didn't work.

This is an old issue but I encountered it again recently with version 1.28.0 of conan. Apart from requiring the right version of conan, check that the conan.cmake file that is downloaded via CMake in your build directory (or${CMAKE_BINARY_DIR}) is not blank, as mine was. There seems to be a problem with the way CMake downloads the file; maybe it just creates the file and does not download it, I'm not sure.
In this case, just download the cmake file from https://github.com/conan-io/cmake-conan/raw/v0.15/conan.cmake and overwrite the one in the build directory with the correct file, or just copy paste the code to the existing file, whichever way suits you better.
