C++ '；openssl/crypto.h'；在vscode上找不到文件

尽管我将include路径添加到openssl，但还是出现了以下编译错误。我在MAC上使用vscode。你能告诉我怎么修吗

错误

main.cpp:3:10: fatal error: 'openssl/crypto.h' file not found
#include <openssl/crypto.h>
         ^

更新1

我发现了类似的问题，但仍然没有为我找到解决方案

---

更新2

我尝试使用g++进行编译，但效果不太好。我的mac是OS X El Capitan版本10.11.6

$ g++ main.cpp -L/usr/local/opt/openssl/lib -lssl -lcrypto -o test
main.cpp:3:10: fatal error: 'openssl/crypto.h' file not found
#include <openssl/crypto.h>
         ^
1 error generated.

另一个解决方案： 在Mac上（但这也适用于其他OSs），我首先更新了openssl：

brew upgrade openssl

然后设置以下环境变量：

export LDFLAGS="-L/usr/local/opt/openssl/lib"
export CPPFLAGS="-I/usr/local/opt/openssl/include"

这是我通过简单的尝试得到的：

brew info openssl

我仍然需要更新tasks.json，但现在更改成功了（c的clang）：
