由于

sqlite3

的版本太旧，我安装了另一个新版本的

sqlite3

。新版本已安装在以下路径中：

/export/home/hh/hh/sqlite/include
/export/home/hh/hh/sqlite/lib

我在

cmake

中修改并使用它来查找新的

sqlite3

。

MESSAGE

的输出显示

cmake

可以找到新版本的

includes

和

libs

：

-- SQLite3 include: /export/home/hh/hh/sqlite/include
-- SQLite3 lib: /export/home/hh/hh/sqlite/lib/libsqlite3.so
-- SQLite3 IS USED

当我安装我的项目时，发生了错误

“sqlite3\u prepare\u v2”未在此范围内声明。但是新版本中包含了sqlite3\u prepare\u v2
，应该声明它。我认为可能的原因是cmake
找不到新版本，而是找到了旧版本。有什么帮助吗？提前谢谢你

sqlite3.h
包含在我的标题中：
#include "sqlite3.h"

在相应的cpp文件中使用sqlite3\u prepare\u v2
。
设置sqlite3\u库
和sqlite3\u在CMakeCache.txt
中包含\u DIRS
（或使用cmake gui），以便它们指向所需的库版本。删除SQLITE3\u FOUND
和SQLITE3\u定义
并重新运行CMake。
向我们展示如何使用CMakeLists.txt
中的find\u包
的结果来编译程序。当然还有你的程序。你好@Tsyvarev我已经更新了帖子。find_package（SQLite3）
设置变量SQLite3\u INCLUDE_DIRS
，但是你使用SQLITE_INCLUDE_DIRS
（没有3
）来包含目录（）
@Tsyvarev抱歉这个错误，我把它改成了SQLite3\u INCLUDE_DIRS
，并重新安装了项目，但出现了数百个错误未定义的引用
。因此您需要取消注释目标链接库
呼叫。您好，感谢您的回复，如何设置SQLITE3_库
和SQLITE3_包含_目录
以及如何删除找到的SQLITE3_和SQLITE3_定义
？你能详细解释一下你的解决方案吗？谢谢。正如我所描述的：您可以使用cmake gui查看所有变量及其值。或者，您可以在生成目录中编辑cmakcache.txt。
