FLTK 1.3 链接错误

Question

我将 FLTK 从 1.1 更新到 1.3，然后我无法编译更新前运行良好的代码。

我尝试在 CMakeLists.txt 中添加一些库，但它不起作用。谁能告诉我\xe2\x80\x99是什么问题？

Answer 1

来自 FLTK 1.3 的 README.CMake.txt：

将 CMAKE 与 FLTK 结合使用

本指南假设您已安装使用 CMake 构建的 FLTK 库。使用 CMake 构建它们会生成一些 CMake 帮助程序文件，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（FLTK需要NO_MODULE）包括（$ {FLTK_USE_FILE}）

add_executable(你好WIN32 hello.cxx)

target_link_libraries（你好fltk）

find_package 命令告诉 CMake 查找包 FLTK，REQUIRED 表示如果没有找到则出错。NO_MODULE 告诉它仅搜索 FLTKConfig 文件，而不使用 CMake 提供的 FindFLTK.cmake，后者不适用于此版本的 FLTK。

找到包后，我们将包含 ${FLTK_USE_FILE}，它将 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 标头，并且当您链接 fltk 库时，它会自动链接 fltk 所依赖的库。

似乎从 FLTK 1.1 到 1.3，他们改变了查找库所需的方法，也许是出于可比性/测试的原因？

我也被同样的问题困扰，希望有人觉得这很有用。:)
