问题：未找到包“libcrypto”

Question

我看到了这个问题“找不到包‘libcrypto’”。我几个月前修复的相同错误是遵循这个解决方案：https : //github.com/scipr-lab/libsnark/issues/99 我今天尝试了这个解决方案，但它不再起作用了。（我也试过“brew install openssl，brew info openssl”）没有运气。你以前见过这个吗？你能帮忙看看吗？

brew info openssl 说如下：（对我来说，如果你的版本不同，对你来说可能会有所不同）

openssl@1.1 is keg-only, which means it was not symlinked into /usr/local,
because openssl/libressl is provided by macOS so don't link an incompatible version.

If you need to have openssl@1.1 first in your PATH run:
  echo 'export PATH="/usr/local/opt/openssl@1.1/bin:$PATH"' >> ~/.zshrc

For compilers to find openssl@1.1 you may need to set:
  export LDFLAGS="-L/usr/local/opt/openssl@1.1/lib"
  export CPPFLAGS="-I/usr/local/opt/openssl@1.1/include"

For pkg-config to find openssl@1.1 you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/openssl@1.1/lib/pkgconfig"

由于您的 CMake 脚本似乎使用了 pkg-config，因此您只需要在运行cmake.
