That is what I thought. Thank you.

Yes, the most efficient way is using conditional setting. For example:

if (CMAKE_SIZEOF_VOID_P EQUAL 4)
  set(import_path /to/lib32)
else()
  set(import_path /to/lib64)
endif()

set_property(TARGET foo PROPERTY IMPORT_LOCATION "${import_path}/lib.so")

Marc,

Appreciate the quick and helpful response.

In a config file that supports multiple platforms, do I need to create import_location_path variable and populate it depending on platform and 32/64 etc? Any other options?

Thanks.

Kind regards, Lars

Properties IMPORTED_LOCATION* do not support generator expressions.

Generally speaking, if a property supports generator expression, it is explicitly specified in documentation.

Hello,

Trying to import an external library but having some issue with setting imported_location_release property.

Basically I have config file which does this;
add_library(foo STATIC IMPORTED)
set_property(target foo APPEND PROPERTY
   interface_include_directories
    "$<BUILD_INTERFACE:${foot_root}/path>"
    "$<INSTALL_INTERFACE:${foo_root}/foo>")

set_property(TARGET foo APPEND PROPERTY
  IMPORTED_LOCATION_RELEASE
    $<$<CXX_COMPILER_ID:GNU>:${foo_root}/lib/release/foo.a>)

The imported target is used in a target_link_libraries method;
target_link_libraries(an_application foo)

Running CMake 3.6.1 does not produce any warnings. Running make I get a "target pattern contains no '%'" error message with a reference to a Build.make file.

The Build.make contains the string " $<$<CXX_COMPILER_ID:GNU>:/tmp/prototype/foo/lib/release/foo.a".  We did not expect to see the generator expression in the Build.make file.

Does set_property support generator expression in this context? What are we doing wrong?

Appreciate any help :-)

king regards, Lars
