ccov-all-export on Windows

[stanczyk4]

Most of the ccov-all commands have an if(WIN32) section to handle command substitution of 'cat ...'. The ccov-all-export does not.
Below is a snippet that fixes that, could you incorporate in next release?

# Export coverage information so continuous integration tools (e.g.
      # Jenkins) can consume it
      if(WIN32)
        add_custom_target(
          ccov-all-export
          COMMAND
            powershell -Command $$FILELIST = Get-Content
            ${CMAKE_COVERAGE_OUTPUT_DIRECTORY}/binaries.list\; llvm-cov.exe
            export $$FILELIST
            -instr-profile=${CMAKE_COVERAGE_OUTPUT_DIRECTORY}/all-merged.profdata
            -format="text" ${EXCLUDE_REGEX} >
            ${CMAKE_COVERAGE_OUTPUT_DIRECTORY}/coverage.json
          DEPENDS ccov-all-processing)
      else()
        add_custom_target(
          ccov-all-export
          COMMAND
            ${LLVM_COV_PATH} export `cat
            ${CMAKE_COVERAGE_OUTPUT_DIRECTORY}/binaries.list`
            -instr-profile=${CMAKE_COVERAGE_OUTPUT_DIRECTORY}/all-merged.profdata
            -format="text" ${EXCLUDE_REGEX} >
            ${CMAKE_COVERAGE_OUTPUT_DIRECTORY}/coverage.json
          DEPENDS ccov-all-processing)
      endif()
