FLTK 1.3链接错误

Question

我将我的FLTK从1.1更新到1.3，然后我无法编译在更新之前运行良好的代码。

我试图在CMakeLists.txt中添加一些库，但是它不起作用。 谁能告诉我这是什么问题？

Answer 1

从FLTK 1.3的README.CMake.txt中：

在FLTK中使用CMAKE

此方法假定您已安装使用CMake构建的FLTK库。 使用CMake构建它们会生成一些CMake帮助文件，这些文件安装在标准位置，使FLTK易于查找和使用。

这是使用FLTK的基本CMakeLists.txt文件。

cmake_minimum_required（版本2.6）

项目（你好）

find_package（需要FLTK的NO_MODULE）include（$ {FLTK_USE_FILE}）

add_executable（您好WIN32 hello.cxx）

target_link_libraries（hello fltk）

---

find_package命令告诉CMake查找软件包FLTK，REQUIRED表示如果未找到，则为错误。 NO_MODULE告诉它仅搜索FLTKConfig文件，而不使用CMake随附的FindFLTK.cmake，该文件不适用于此版本的FLTK。

找到包后，我们将包含$ {FLTK_USE_FILE}，该文件将FLTK包含目录和库链接信息添加到其知识库中。 之后，您的程序将能够找到FLTK头，并且当您链接fltk库时，它会自动链接fltk所依赖的库。

从FLTK 1.1到1.3，似乎是出于可比性/测试原因，他们更改了查找库所需的方法？

我挂在同一问题上，希望有人觉得这有用。 :)
