根因分析
install(EXPORT) 命令引用的目标之前没有使用相同的 EXPORT 名称通过 install(TARGETS) 注册。
English
An install(EXPORT) command references a target that was not previously registered with install(TARGETS) and the same EXPORT name.
官方文档

-
确保目标使用相同的 EXPORT 名称安装：install(TARGETS mylib EXPORT MyTargets DESTINATION lib)。然后 install(EXPORT MyTargets DESTINATION lib/cmake)。示例：install(TARGETS mylib EXPORT MyTargets DESTINATION lib) 和 install(EXPORT MyTargets DESTINATION lib/cmake/MyProject)。
-
如果目标不应被导出，将其从 install(EXPORT) 调用中移除，或为其创建单独的导出集。
无效尝试
常见但无效的做法:
-
90% 失败
CMake uses the EXPORT name to group targets; mismatched names cause the target to be omitted from the set.
-
95% 失败
Without the export, other projects cannot use find_package to locate the installed targets.
