根因分析

在 install(EXPORT ...) 中列出的目标未事先通过 install(TARGETS ...) 注册到该导出集。

English

A target listed in install(EXPORT ...) was not previously registered with install(TARGETS ...) for that export set.

解决方案

  1. Ensure every target in install(EXPORT ...) is also installed with install(TARGETS ... EXPORT ...) using the same export set name.
  2. If the target is header-only, use install(TARGETS mylib EXPORT MyTargets) with an INTERFACE library.

无效尝试

常见但无效的做法:

  1. Adding the target to the export set by adding it to install(EXPORT ...) without install(TARGETS ...) 95% 失败

    The target must be explicitly installed with install(TARGETS ...) first; just listing it in install(EXPORT ...) does not register it.

  2. Removing the target from the export list, assuming it's not needed 70% 失败

    If the target is required by downstream projects, removing it breaks the export and causes missing dependencies.

  3. Using install(TARGETS ... EXPORT MyTargets) but misspelling the export set name 80% 失败

    Mismatched export set names cause the target to be registered under a different set, leading to the same error.
