我正在尝试在 Linux 上将 glfw 库构建为共享库。我已经开始克隆 git repository .然后，根据this编译指南，我在 repo 中创建了一个名为 glfw-build 的文件夹，然后 cd 进入了它。 Runnnig cmake .. 从那里给出输出

我似乎得到的只是一个 a 文件，即静态库，但如前所述，我需要一个共享库，即 so 文件。
为什么我得不到so文件；这不应该是默认的吗？我怎样才能得到它？
最佳答案
一些项目(glfw3 其中)隐含地允许用户通过 BUILD_SHARED_LIBS 影响他们生成的库类型变量:
If present and true, this will cause all libraries to be built shared unless the library was explicitly added as a static library. This variable is often added to projects as an OPTION so that each user of a project can decide if they want to build the project using shared or static libraries.
配置
cmake -DBUILD_SHARED_LIBS=ON ..
告诉项目生成共享库。
请注意，如果您希望两种类型的库都存在于您的系统中，您需要为它们分配不同的安装前缀(CMAKE_INSTALL_PREFIX 变量)。
并非所有项目都允许进行此类调整。一些项目自己选择构建类型。其他一些人为此目的使用另一个变量。只需阅读项目的自述文件或检查其代码。
