support OUTPUT_QUIET and ERROR_QUIET in conan_cmake_install

[RalfBielig]

problem:

• line 534 option OUTPUT_QUIET is missing
• would be nice to add ERROR_QUIET as well

possible solution:

see:

cmake-conan/conan.cmake

Line 615 in c782959

if(ARGS_OUTPUT_QUIET)

replace:

    if(ARGS_OUTPUT_QUIET)
        execute_process(COMMAND ${CONAN_CMD} ${install_args}
                        RESULT_VARIABLE return_code
                        OUTPUT_VARIABLE conan_output
                        ERROR_VARIABLE conan_output
                        WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR})
    else()
        execute_process(COMMAND ${CONAN_CMD} ${install_args}
                        RESULT_VARIABLE return_code
                        WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR})
    endif()

by:

    if(ARGS_OUTPUT_QUIET)
      set(OUTPUT_OPT OUTPUT_QUIET)
    endif()
    if(ARGS_ERROR_QUIET)
      set(ERROR_OPT ERROR_QUIET)
    endif()
    execute_process(COMMAND ${CONAN_CMD} ${install_args}
                    RESULT_VARIABLE return_code
                    ${OUTPUT_OPT}
                    ${ERROR_OPT}
                    WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR})
