我尝试使用CMake制作crypt(3)样本。

#define _GNU_SOURCE

#include <stdio.h>
#include <string.h>
#include <unistd.h>
#include <crypt.h>

/* To compile: $ gcc check.c -lcrypt -o check */
int main(void) {
  /* Hashed form of "GNU libc manual". */
  char *pass = "$1$/iSaq7rB$EoUw5jJPPvAPECNaaWzMK/";
  /* Read in the user’s password and encrypt it,
     passing the expected password in as the salt. */
  char *result = crypt(getpass("Password:"), pass);
  /* Test the result. */
  int ok = strcmp (result, pass) == 0;

  puts(ok ? "Access granted." : "Access denied.");
  return ok ? 0 : 1;
} 

要构建它,应该将-lcrypt选项传递给gcc。 我的CMakeLists.txt看起来像是:

project(cryptexample)
set(SOURCE_FILES check.c)
add_executable(check ${SOURCE_FILES})

如何通过此选项并构建它?

类似的东西:

target_link_libraries(check crypt)
