Root Cause

The install(TARGETS) command must specify a destination or component for each target type; otherwise, CMake does not know where to place the installed files.

generic

中文

install(TARGETS) 命令必须为每种目标类型指定目标路径或组件；否则 CMake 不知道将安装文件放在哪里。

Workarounds

  1. 95% success Add DESTINATION for each target type: install(TARGETS mylib RUNTIME DESTINATION bin LIBRARY DESTINATION lib ARCHIVE DESTINATION lib/static). Example: install(TARGETS myapp RUNTIME DESTINATION bin). 
    Add DESTINATION for each target type: install(TARGETS mylib RUNTIME DESTINATION bin LIBRARY DESTINATION lib ARCHIVE DESTINATION lib/static). Example: install(TARGETS myapp RUNTIME DESTINATION bin).
  2. 90% success Use a single DESTINATION for all components: install(TARGETS mylib DESTINATION lib). This works for simple libraries that don't separate runtime/archive.

中文步骤

  1. 为每种目标类型添加 DESTINATION：install(TARGETS mylib RUNTIME DESTINATION bin LIBRARY DESTINATION lib ARCHIVE DESTINATION lib/static)。示例：install(TARGETS myapp RUNTIME DESTINATION bin)。
  2. 为所有组件使用单一 DESTINATION：install(TARGETS mylib DESTINATION lib)。这适用于不分离运行时/存档的简单库。

Dead Ends

Common approaches that don't work:

  1. 80% fail

    If a target produces both a runtime and a library, both must have destinations; specifying only one leaves the other undefined.

  2. 95% fail

    CMAKE_INSTALL_PREFIX sets the root, but install(TARGETS) needs explicit DESTINATION relative to that root.
