CMake库输出的自定义目录 [英] Custom Directory for CMake Library Output

问题描述

在CMake，我似乎不能输出我的库在../out/library，只有库。当我做../out/library路径时，它告诉我找不到库，好像想链接到它。

In CMake, I can't seem to output my library in ../out/library, only library. When I do the ../out/library path, it tells me it can't find the library, as if it wants to link to it.

add_library(../out/JE3D ../source/CDeviceLayerSDL.cpp)

还有更多的文件，我只是节省空间。当我这样做，我得到这个错误。

There's more files, I'm just saving space. When I do that, I get this error.

链接CXX静态库lib ../ out / JE3D.a

推荐答案

目标属性指定库目标文件所在目录的 LIBRARY_OUTPUT_DIRECTORY

The LIBRARY_OUTPUT_DIRECTORY target property specifies the directory where library target files will be built.

set_target_properties(JE3D PROPERTIES
         LIBRARY_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/out/library)

如果所有的库都在一个目录下，我发现更方便的设置 CMAKE_LIBRARY_OUTPUT_DIRECTORY 变量，用于在创建目标时初始化 LIBRARY_OUTPUT_DIRECTORY 属性。

If all the libraries are in one directory, I find it more convenient to set the CMAKE_LIBRARY_OUTPUT_DIRECTORY variable, which is used to initialize the LIBRARY_OUTPUT_DIRECTORY property when creating a target.

set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${PROJECT_BINARY_DIR}/out/library)

修改：如果您的目标是静态库，请检查评论

Check comments if your target is a static library
