This changes the type of the `argv` parameter in the `main` function to match the expected signature for integration with the CMake testing framework. By default, the test driver expects the main function to have the following signature: ``` typedef int (*MainFuncPointer)(int, char* []); ``` See https://github.com/Kitware/CMake/blob/master/Templates/TestDriver.cxx.in This fixes a link error when building PythonQtCppTests on Windows: ``` 1>PythonQtCppTests.obj : error LNK2001: unresolved external symbol "int __cdecl tests_PythonQtTestMain(int,char * * const)" (?tests_PythonQtTestMain@@YAHHQEAPEAD@Z) 1>C:\temp\PythonQt-build\Debug\PythonQtCppTests.exe : fatal error LNK1120: 1 unresolved externals ``` (cherry picked from commit commontk/PythonQt@aa1a16f)
This change ensures that the main function signatures in all example files are consistent.

The changes ensure that the main function signatures in the generator, test and example files is consistent.
It updates the
argvparameter type fromchar **argvtochar *argv[]and resolves a specific link error encountered when buildingPythonQtCppTestson Windows.This will be helpful to integrate with the CMake/CTest testing framework. By default, the CMake test driver1 expects the main function to have the following signature:
This will fix link errors like the following when building
PythonQtCppTestson Windows:Note
