2. 解决办法
就是报告没有安装openssl，但是我在命令行下执行openssl时找到了已经安装的openssl，而且重复安装会报错:
cmake-3.18.0$ openssl version
OpenSSL 1.1.1 11 Sep 2018
cmake-3.18.0$$ sudo apt-get install openssl
[sudo] password for t31:
Reading package lists... Done

Reading state information... Done
openssl is already the newest version (1.1.1-1ubuntu2.1~18.04.20).
The following packages were automatically installed and are no longer required:
linux-hwe-5.4-headers-5.4.0-109 linux-hwe-5.4-headers-5.4.0-110 linux-hwe-5.4-headers-5.4.0-113 linux-hwe-5.4-headers-5.4.0-117 linux-hwe-5.4-headers-5.4.0-120 linux-hwe-5.4-headers-5.4.0-121
linux-hwe-5.4-headers-5.4.0-122 linux-hwe-5.4-headers-5.4.0-84
Use 'sudo apt autoremove' to remove them.
0 upgraded, 0 newly installed, 0 to remove and 44 not upgraded.
最后发现是缺少openssl的开发版本，安装如下:
sudo apt-get install libssl-dev
