How to set CMAKE_INSTALL_RPATH with multiple directories?

On the question CMAKE RPATH not working - could not find shared object file I see how to set CMAKE_INSTALL_RPATH for a single path, but I need it for multiple paths. I tried these using but I did not worked:

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

On the question How to set multiple RPATH directories using CMake on MacOS I see I can set multiple paths with semicolon ; for a target, but I would like to set it for all targets instead of setting it for each one. Is there a equivalent of set_target_properties for all targets (including subprojects) ? For example:

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

After testing, it seems the first option using semicolons as separator is working SET( CMAKE_INSTALL_RPATH "/opt/my/lib;/other/lib" ). For reference, there is the cmake documentation, but I did not found this answer there: https://gitlab.kitware.com/cmake/community/-/wikis/doc/cmake/RPATH-handling

The thing I do not know about is how I can use something like set_target_properties for all my alltargets automatically.

Snippet:

# 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()
