英文:
CMake link external shared lib on linux?
问题
我尝试在Linux上使用CMake链接外部库。编译和构建都正常。但当我运行它时，它显示以下错误：
./test/calculator_test: error while loading shared libraries: ../../../third_party/add/lib/add.so: cannot open shared object file: No such file or directory
文件树（我删除了一些不必要的部分）：
├── CMakeLists.txt├── build├── src├── test│ ├── CMakeLists.txt│ └── calculator│ ├── CMakeLists.txt│ └── calculator_test.cpp└── third_party├── add│ ├── include│ │ └── add.h│ └── lib│ └── add.so└── googletest...
test/calculator/CMakeLists.txt：
add_library(lib-add SHARED IMPORTED)set_target_properties(lib-addPROPERTIESIMPORTED_LOCATION "${PROJECT_SOURCE_DIR}/third_party/add/lib/add.so"INTERFACE_INCLUDE_DIRECTORIES "${PROJECT_SOURCE_DIR}/third_party/add/include")add_executable(calculator_test calculator_test.cpp)target_link_libraries(calculator_test PRIVATE lib-add lib-sub)set_target_properties(calculator_testPROPERTIESRUNTIME_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/test"COMMAND calculator_test)
那么为什么会出现这个错误，如何修复它呢？
英文:
I try to link an external libaray on Linux in CMake.
The compile and make are fine.
But when I run it, it says:
./test/calculator_test: error while loading shared libraries: ../../../third_party/add/lib/add.so: cannot open shared object file: No such file or directory
File tree (I remove some unnecessary part):
├── CMakeLists.txt├── build├── src├── test│ ├── CMakeLists.txt│ └── calculator│ ├── CMakeLists.txt│ └── calculator_test.cpp└── third_party├── add│ ├── include│ │ └── add.h│ └── lib│ └── add.so└── googletest...
test/calculator/CMakeLists.txt:
add_library(lib-add SHARED IMPORTED)set_target_properties(lib-addPROPERTIESIMPORTED_LOCATION "${PROJECT_SOURCE_DIR}/third_party/add/lib/add.so"INTERFACE_INCLUDE_DIRECTORIES "${PROJECT_SOURCE_DIR}/third_party/add/include")add_executable(calculator_test calculator_test.cpp)target_link_libraries(calculator_test PRIVATE lib-add lib-sub)set_target_properties(calculator_testPROPERTIESRUNTIME_OUTPUT_DIRECTORY "${CMAKE_BINARY_DIR}/test"COMMAND calculator_test)
So why and how to make it correct?

我认为这是CMake的一个错误。
我在使用3.22.1（Ubuntu 22.04）时遇到了这个问题。升级到CMake 3.27后问题解决了。看起来这个问题在CMake 3.24中已经修复了。

I think it is a bug of cmake.
I see the problem when using 3.22.1 (Ubuntu 22.04). After upgrading to cmake 3.27 it works. It seems it was fixed in cmake 3.24.
