The following issue has been SUBMITTED. ====================================================================== http://public.kitware.com/Bug/view.php?id=15299 ====================================================================== Reported By: Paweł Stankowski Assigned To: ====================================================================== Project: CMake Issue ID: 15299 Category: Modules Reproducibility: always Severity: major Priority: normal Status: new ====================================================================== Date Submitted: 2014-12-11 06:36 EST Last Modified: 2014-12-11 06:36 EST ====================================================================== Summary: CMakeExpandImportedTargets does not support generator expression TARGET_PROPERTY w/o target specified Description: CMakeExpandImportedTarget expands target names to file paths including targets from IMPORTED_LINK_INTERFACE_LIBRARIES* properties of expanded targets.
However, IMPORTED_LINK_INTERFACE_LIBRARIES property may contain generator expression $<TARGET_PROPERTY:prop>. It should be converted to $<TARGET_PROPERTY:target,prop> expression. Otherwise following error will appear: "$<TARGET_PROPERTY:prop> may only be used with targets. It may not be used with add_custom_command. Specify the target to read a property from using the $<TARGET_PROPERTY:tgt,prop> signature instead". BTW: INTERFACE_LINK_LIBRARIES property should be preferred, IMPORTED_LINK_INTERFACE_LIBRARIES should not be used when the former is defined. Currently INTERFACE_LINK_LIBRARIES property is ignored. Steps to Reproduce: This is easily reproducible on Windows with Qt libraries. For example, Qt5 adds following generator expression in IMPORTED_LINK_INTERFACE_LIBRARIES of Qt targets: $<$<AND:$<STREQUAL:$<TARGET_PROPERTY:TYPE>,EXECUTABLE>,$<BOOL:$<TARGET_PROPERTY:WIN32_EXECUTABLE>>,$<NOT:$<BOOL:$<TARGET_PROPERTY:Qt5_NO_LINK_QTMAIN>>>,$<TARGET_POLICY:CMP0020>>:Qt5::WinMain>;C:/Qt5/5.3/msvc2013_opengl/bin/Qt5Networkd.dll;C:/Qt5/5.3/msvc2013_opengl/bin/Qt5Cored.dll;$<$<AND:$<STREQUAL:$<TARGET_PROPERTY:TYPE>,EXECUTABLE>,$<BOOL:$<TARGET_PROPERTY:WIN32_EXECUTABLE>>,$<NOT:$<BOOL:$<TARGET_PROPERTY:Qt5_NO_LINK_QTMAIN>>>,$<TARGET_POLICY:CMP0020>>:Qt5::WinMain> Qt4 does similar thing. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2014-12-11 06:36 Paweł StankowskiNew Issue ====================================================================== -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
