             Bug #: 13147
           Summary: CMake-generated Makefiles block one library's source
                    files on the previous library's link step
           Product: Build scripts
           Version: trunk
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: cmake
        AssignedTo: unassignedbugs at nondot.org
        ReportedBy: scshunt at csclub.uwaterloo.ca
                CC: llvmbugs at cs.uiuc.edu
    Classification: Unclassified


The CMake-generated Makefiles will not build the source files in one library
until after the previous library's link step has been completed. This means
that highly parallel builds are often limited by the number of source files
that they can build in a single library at a time. This dependency should be
removed so that builds can be done concurrently across multiple libraries, and
only the link steps should depend on each other.
