cmake - 如何设置 CMAKE_INSTALL_RPATH 多个目录？

Question

关于问题CMAKE RPATH not working - could not find shared object file我看看如何设置CMAKE_INSTALL_RPATH对于单个路径，但我需要它用于多个路径。我尝试使用这些，但没有成功:

SET( CMAKE_INSTALL_RPATH "/opt/my/lib;/other/lib" )
SET( CMAKE_INSTALL_RPATH "/opt/my/lib:/other/lib" )

关于问题How to set multiple RPATH directories using CMake on MacOS我看到我可以用分号设置多个路径 ;对于一个目标，但我想为所有目标设置它，而不是为每个目标设置它。有相当于 set_target_properties 的吗？对于所有目标(包括子项目)？例如:

set_target_properties(alltargets
    PROPERTIES
    INSTALL_RPATH "/opt/my/lib;/other/lib"
)

片段:

# note: macOS is APPLE and also UNIX !
if(APPLE)
  set_target_properties(foo PROPERTIES
    INSTALL_RPATH "@loader_path;@loader_path/...")
elseif(UNIX)
  set_target_properties(foo PROPERTIES
    INSTALL_RPATH "$ORIGIN:$ORIGIN/...")
endif()
