根因分析

通过 add_library(MyPackage::MyLib UNKNOWN IMPORTED) 或类似方式创建的导入目标缺少 IMPORTED_LOCATION 属性，而该属性是链接所必需的。

English

An imported target created via add_library(MyPackage::MyLib UNKNOWN IMPORTED) or similar lacks the IMPORTED_LOCATION property, which is required for linking.

解决方案

  1. add_library(MyPackage::MyLib UNKNOWN IMPORTED)
set_target_properties(MyPackage::MyLib PROPERTIES
  IMPORTED_LOCATION "/usr/local/lib/libmylib.so"
)
  2. # In MyPackageConfig.cmake:
add_library(MyPackage::MyLib UNKNOWN IMPORTED)
set_target_properties(MyPackage::MyLib PROPERTIES
  IMPORTED_LOCATION "${CMAKE_CURRENT_LIST_DIR}/lib/libmylib.so"
)

无效尝试

常见但无效的做法:

  1. 100% 失败

    CMake requires a non-empty path; an empty string causes the same error or undefined behavior.

  2. 95% 失败

    The property name must match exactly; misspelling leads to the same error.
