根因分析

尝试在 INTERFACE 库目标上设置源文件，而根据定义，INTERFACE 库不能有编译源文件。

English

Attempting to set source files on an INTERFACE library target, which by definition cannot have compile sources.

解决方案

  1. Remove SOURCES from the INTERFACE library. If you need compiled sources, use add_library(mylib STATIC ...) or add_library(mylib SHARED ...) instead.
  2. If you need both interface properties and compiled sources, create two targets: an INTERFACE library for headers and a STATIC/SHARED library for sources, then link them.

无效尝试

常见但无效的做法:

  1. Adding SOURCES property with set_property(TARGET mylib PROPERTY SOURCES ...) to work around the error 95% 失败

    INTERFACE libraries are header-only or pure-interface; they have no compiled sources, so setting SOURCES violates the target type.

  2. Changing the target type to STATIC or SHARED but keeping the same interface logic 70% 失败

    Changing target type changes the build semantics; INTERFACE libraries are intended for header-only or transitive dependencies, not compiled code.

  3. Deleting the target entirely and re-adding it with sources as a different target 80% 失败

    This loses the interface propagation properties and may break dependency chains.
