在使用vcpkg成功安装库之后，使用cmake进行构建的时候一直提示找不到包，如下所示

我这里安装时调用的是

vcpkg install sqlpp11

CMake Error at CMakeLists.txt:4 (find_package):
  Could not find a package configuration file provided by
  "unofficial-sqlite3" with any of the following names:

    unofficial-sqlite3Config.cmake
    unofficial-sqlite3-config.cmake

  Add the installation prefix of "unofficial-sqlite3" to CMAKE_PREFIX_PATH or
  set "unofficial-sqlite3_DIR" to a directory containing one of the above
  files.  If "unofficial-sqlite3" provides a separate development package or
  SDK, be sure it has been installed.

 最后发现在CMakeLists.txt里面需要添加这样一行，这里是我本机的vcpkg路径，需要根据自己电脑安装位置填写

include(/home/ubuntu/home/vcpkg/scripts/buildsystems/vcpkg.cmake)

成功解决问题

完整CMakeLists.txt文件如下所示：

cmake_minimum_required(VERSION 3.0)
project(test)

include(/home/ubuntu/home/vcpkg/scripts/buildsystems/vcpkg.cmake)
find_package(unofficial-sqlite3 CONFIG REQUIRED)

add_executable(testvcpkg test_vcpkg.cpp)

target_link_libraries(testvcpkg PRIVATE unofficial::sqlite3::sqlite3)

test_vcpkg,.cpp 文件如下所示

#include <iostream>
#include <sqlite3.h>

int main() {
  sqlite3 *db;
  int rc = sqlite3_open("test.db", &db);
  if (SQLITE_OK == rc) {
    std::cout << "Hello Geek! The SQLite database opened successfully! \n";
    sqlite3_close(db);
  } else {
    std::cout << "Can't open the SQLite database: " << sqlite3_errmsg(db) << "\n";
  }
  return 0;
}

编译命令

cmake -G Ninja -S . -B build -DCMAKE_BUILD_TYPE=Release -DCMAKE_TOOLCHAIN_FILE=/home/ubuntu/home/vcpkg/scripts/buildsystems/vcpkg.cmake
