Hi Lars.

The DESTINATION parameter of install() accepts only a single argument, which 
means it's tripping on the line break between the two genexes. Make it one 
argument:

INSTALL(FILES ${qt5_locations}
  DESTINATION
    $<$<PLATFORM_ID:Windows>:bin>$<$<PLATFORM_ID:Linux>:lib>
  COMPONENT runtime)

This should work.

Hello,

We use find_package command in config mode to find Qt 5.11 libraries. The 
libraries are available as imported (Qt5::Core etc).

Our understand is that CMake does not support install of imported targets. 
Therefore we use get_target_property to find actual location of library and 
Install(Files ...) to install the files.

The install command looks like this (and works);
INSTALL(FILES ${qt5_locations} DESTINATION "bin" COMPONENT runtime)

The documentation states that DESTINATION supports generator expression. We 
would like to use generator expression to install libraries in "bin" on Windows 
and "lib" on Linux but have not be able to accomplish this task. The below 
command generated the following error message "Install files given unknown 
argument  $<$<PLATFORM_ID:Linux>:lib>". We have tried other variants but none 
of them work.

INSTALL(FILES ${qt5_locations}
  DESTINATION
    $<$<PLATFORM_ID:Windows>:bin>
    $<$<PLATFORM_ID:Linux>:lib>
  COMPONENT runtime)

Appreicate any input.

kind regards, Lars
