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

问题描述

在 CMake 中，我似乎无法在 ../out/library 中输出我的库，只能输出库.当我执行 ../out/library 路径时，它告诉我它找不到库，好像它想链接到它一样.

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)

还有更多文件，我只是节省空间.当我这样做时，我收到此错误.

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/usr/bin/ar: lib../out/JE3D.a: 没有那个文件或目录make[2]: * [lib../out/JE3D.a] 错误 1make[1]: * [CMakeFiles/../out/JE3D.dir/all] 错误 2make: *** [all] 错误 2

Linking CXX static library lib../out/JE3D.a /usr/bin/ar: lib../out/JE3D.a: No such file or directory make[2]: * [lib../out/JE3D.a] Error 1 make[1]: * [CMakeFiles/../out/JE3D.dir/all] Error 2 make: *** [all] Error 2

推荐答案

LIBRARY_OUTPUT_DIRECTORY 目标属性指定将构建库目标文件的目录.

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)

如果所有库都在一个目录中，我发现设置 CMAKE_LIBRARY_OUTPUT_DIRECTORY 变量更方便，该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)

如果您的目标是静态库，请检查评论

Check comments if your target is a static library
