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 ...

CMakeLists.txt:174 (get_prerequisites)When get_prerequisites() is not called, the build
works correctly. 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.
