Question

我正在为我的学校项目建立一个新的数据库，但是即使在Clion之外，我也无法编译任何代码。

经过一些研究，我能够使cmakelist工作，但是当我尝试构建项目时，它不起作用。


package com.example.tulio.appkolev.sql;


public class DatabaseHelper  extends SQLiteOpenHelper{

    private static final int DATABASE_VERSION = 1;

    private static final String DATABASE_NAME = "UserManager.db";

    private static final String TABLE_USER = "user";

    private static final String COLUMN_USER_ID = "user_id";
    private static final String COLUMN_USER_NAME = "user_name";
    private static final String COLUMN_USER_EMAIL = "user_email";
    private static final String COLUMN_USER_PASSWORD = "user_password";

    private String CREATE_USER_TABLE = "CREATE TABLE " + TABLE_USER + "("
            + COLUMN_USER_ID + " INTEGER PRIMARY KEY AUTOINCREMENT," + COLUMN_USER_NAME + " TEXT,"
            + COLUMN_USER_EMAIL + " TEXT," + COLUMN_USER_PASSWORD + " TEXT" + ")";

    private String DROP_USER_TABLE = "DROP TABLE IF EXISTS " + TABLE_USER;

    public DatabaseHelper(Context context){
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db){
        db.execSQL(CREATE_USER_TABLE);
    }

    @Override
    public  void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion){
        db.execSQL(DROP_USER_TABLE);
        onCreate(db);
    }

    public void addUser(User user){
        SQLiteDatabase db = this.getWritableDatabase();
        ContentValues values = new ContentValues();
        values.put(COLUMN_USER_NAME, user.getName());
        values.put(COLUMN_USER_EMAIL, user.getEmail());
        values.put(COLUMN_USER_PASSWORD, user.getPassword());

        db.insert(TABLE_USER, null, values);
        db.close();
    }

    public boolean checkUser(String email){
        String[] columns = {
                COLUMN_USER_ID
        };
        SQLiteDatabase db = this.getWritableDatabase();
        String selection = COLUMN_USER_EMAIL + " = ?";
        String[] selectionArgs = { email };

        Cursor cursor = db.query(TABLE_USER,
                columns,
                selection,
                selectionArgs,
                null,
                null,
                null);
        int cursorCount = cursor.getCount();
        cursor.close();
        db.close();

        if (cursorCount > 0){
            return true;
        }
        return false;
    }

    public boolean checkUser(String email, String password){
        String[] columns = {
                COLUMN_USER_ID
        };
        SQLiteDatabase db = this.getWritableDatabase();
        String selection = COLUMN_USER_EMAIL + " = ?" + " AND " + COLUMN_USER_PASSWORD + " =?";
        String[] selectionArgs = { email, password };

        Cursor cursor = db.query(TABLE_USER,
                columns,
                selection,
                selectionArgs,
                null,
                null,
                null);
        int cursorCount = cursor.getCount();
        cursor.close();
        db.close();

        if (cursorCount > 0){
            return true;
        }
        return false;
    }
}

这是我得到的错误

cmake_minimum_required(VERSION 3.13)
project(TP_BD)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++14")


set(PostgreSQL_ROOT "C:\\Program Files\\PostgreSQL\\11")
find_package(PostgreSQL REQUIRED IMPORTED)

include_directories (${PostgreSQL_INCLUDE_DIRS})
link_directories(${PostgreSQL_LIBRARY_DIRS})


set(SOURCES main.cpp)

add_executable(TP_BD ${SOURCES})
target_link_libraries(TP_BD ${PostgreSQL_LIBRARIES})

set(SOURCE_FILES CMakeLists.txt main.cpp)

此cmakeList的cionList有什么问题？
