[CMake] get_prerequisites() - fails with No such file or directory

[rozelak at volny.cz]

Hallo.I try to use get_prerequisites() and it seems that it is called before the target is created. The CMake code snipped is as follows:    set(SRC_FILES ....)    # Make lib    add_library(          OUTPUT SHARED ${SRCS_FILES})    target_link_libraries(OUTPUT ${PROJECT_LIBRARIES})    target_link_libraries(OUTPUT ${PYTHON_LIBRARIES})    # Install    install(TARGETS       OUTPUT   RUNTIME DESTINATION ./ COMPONENT Runtime                                   LIBRARY DESTINATION ./ COMPONENT Runtime)    # ---    include(GetPrerequisites)    string(TOUPPER ${CMAKE_BUILD_TYPE} CONFIG)    get_target_property(LOC OUTPUT LOCATION_${CONFIG})    ##    message("---> location = ${LOC}")    ##    get_prerequisites(${LOC} PREREQS 0 0 "" "")    ##    message("---> prerequisites: ${PREREQS}")    foreach(D ${PREREQS})            message("    ---> ${D}")    endforeach()    ###but it seems that get_prerequisites() is called before the target is created (the sources are compiled and library is link
 ed). It results in the following error messages.Under Linux:    -- The C compiler identification is GNU 4.8.3    -- The CXX compiler identification is GNU 4.8.3    -- Check for working C compiler: /usr/bin/cc    -- Check for working C compiler: /usr/bin/cc -- works    -- Detecting C compiler ABI info    -- Detecting C compiler ABI info - done    -- Check for working CXX compiler: /usr/bin/c++    -- Check for working CXX compiler: /usr/bin/c++ -- works    -- Detecting CXX compiler ABI info    -- Detecting CXX compiler ABI info - done    ...

So, did I do anything wrong?Thank you very much. Best regards,Dan T.P.S. I use cmake 3.0.2 under Linux and 3.4.0-rc2 on windows.
