ssh_connect: Library not initialized (LibSSH) - c++

Question

I have the following piece of code which I am trying to build statically, so I end up with a single executable.
#define LIBSSH_STATIC 1
#include <libssh/libssh.h>
#include <stdlib.h>
#include <stdio.h>
#include <iostream>
#include <errno.h>
#include <string.h>
#pragma comment(lib, "mbedcrypto.lib")
#pragma comment(lib, "pthreadVSE3.lib")
#pragma comment(lib, "ssh.lib")
#pragma comment(lib, "Ws2_32.lib")
int main()
{
ssh_session my_ssh_session;
int method, rc;
int port = 22;
const char* password;
int verbosity = SSH_LOG_FUNCTIONS;
//int stricthostcheck = 0;
std::string host = "10.10.10.100";
std::string user = "user";
// Open session and set options
my_ssh_session = ssh_new();
if (my_ssh_session == NULL)
exit(-1);
ssh_options_set(my_ssh_session, SSH_OPTIONS_HOST, host.c_str());
ssh_options_set(my_ssh_session, SSH_OPTIONS_PORT, &port);
ssh_options_set(my_ssh_session, SSH_OPTIONS_USER, user.c_str());
ssh_options_set(my_ssh_session, SSH_OPTIONS_LOG_VERBOSITY, &verbosity);
// Connect to server
rc = ssh_connect(my_ssh_session);
if (rc != SSH_OK)
{
fprintf(stderr, "Error: %s\n", ssh_get_error(my_ssh_session));
ssh_free(my_ssh_session);
exit(-99);
}
// Authenticate ourselves
password = "Password";
rc = ssh_userauth_password(my_ssh_session, NULL, password);
if (rc != SSH_AUTH_SUCCESS)
{
fprintf(stderr, "Error authenticating with password: %s\n",
ssh_get_error(my_ssh_session));
ssh_disconnect(my_ssh_session);
ssh_free(my_ssh_session);
exit(-1);
}
ssh_disconnect(my_ssh_session);
ssh_
free(my_ssh_session);
}
I have installed the following libraries using VCPKG
libssh:x86-windows-static
zlib:x86-windows-static
openssh:x86-windows-static
I have manually linked the following include path, in the C/C++ section of project properties on the General tab under Additional include directories
C:\dev\vcpkg\installed\x64-windows-static\include
I have also under in the Linker section of project properties, also on its General tab, added an entry for Additional library directories
C:\dev\vcpkg\installed\x64-windows-static\lib
The additional libraries are linked in the code, using the following four lines of code:
#pragma comment(lib, "mbedcrypto.lib")
#pragma comment(lib, "pthreadVSE3.lib")
#pragma comment(lib, "ssh.lib")
#pragma comment(lib, "Ws2_32.lib")
I have also set the C/C++, Code Generation, Runtime option to Multi-Threaded (/MT)
When I run the program it compiles fine, creating a single executable. However, when I run the program, I get an error stating "ssh_connect: Library not initialized"
This is day three of trying to get this to work, with no previous knowledge of how to compile applications. Any help greatly appreciated :)

3 days spent on guessing instead of reading the manual - it's unbelievable. Almost on the top:
If libssh is statically linked, threading must be initialized by calling
ssh_init() before using any of libssh provided functions. This initialization
must be done outside of any threading context. Don't forget to call
ssh_finalize() to avoid memory leak
By the way, any examples of libbssh usage have calls to ssh_init() and ssh_finalize(). You can look at the unit tests.
