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.
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
