Solve the problem of slow CDB debugging speed

        On the windows platform, when Qt uses the CDB debugger tool to debug the program, there is often a debugging card for half a day. There are two reasons for this problem:
        Reason 1: The program has enabled the incremental connection function;
        Reason 2: Qt is in the background Download the *.pdb file for program debugging from the Microsoft Symbol server ; the
        solution is as follows:
        1. In the *.pro project file, disable incremental connection and add the following statement:

QMAKE_LFLAGS_DEBUG += /INCREMENTAL:NO

        2. Download all the *.pdb files required by the program at one time, and then directly access the local Symbol file without downloading in the background;
        open Qt, click [Tools] –> Options –> Debugger – on the Qt toolbar > CDB Paths --> In Symbol Paths, fill in the following:

cache*D:\CDBsymbolcache
srv*http://msdl.microsoft.com/download/symbols

Figure (1) Fill in the Symbol path in Qt's CDB Paths

        3. Remove the following "srv*http://msdl.microsoft.com/download/symbols" statement and no longer download in the background, as follows:

Figure (2) Remove the following service address and only keep the local cache

        The main reason is the second reason, the CDB debugging speed is imaged. It is recommended to remove the server address after the Symbol is downloaded.
