error: failed to run custom build command for `openssl-sys

 Caused by:

   The pkg-config command could not be found.                           
                                                                        
   Most likely, you need to install a pkg-config package for            
 your OS.                                                               
   Try `apt install pkg-config`, or `yum install pkg-config`,           
   or `pkg install pkg-config`, or `apk add pkgconfig`                  
 depending on your distribution.                                        
                                                                        
   If you've already installed it, ensure the pkg-config                
 command is one of the                                                  
   directories in the PATH environment variable.                        
                                                                        
   If you did not expect this build to link to a pre-installed          
 system library,                                                        
   then check documentation of the openssl-sys crate for an             
 option to                                                              
   build the library from source, or disable features or                
 dependencies                                                           
   that require pkg-config.

   Could not find directory of OpenSSL installation, and this

 this crate had                                                         
   trouble finding it,  you can set the `OPENSSL_DIR`                   
 environment variable for the                                           
   compilation process.                                                 
                                                                        
   Make sure you also have the development packages of openssl          
 installed.                                                             
   For example, `libssl-dev` on Ubuntu or `openssl-devel` on            
 Fedora.                                                                
                                                                        
   If you're in a situation where you think the directory               
 *should* be found

   It looks like you're compiling on Linux and also targeting           
 Linux. Currently this                                                  
   requires the `pkg-config` utility to find OpenSSL but                
 unfortunately `pkg-config`                                             
   could not be found. If you have OpenSSL installed you can            
 likely fix this by                                                     
   installing `pkg-config`.
