Error #4 launching Easy-PQXX.bat

[francescoBLT]

Hi
I'm attempting to compile the library but I have reported error. I've installed:
Cmake 3.12.2
PostgresSQL version 12
Visual studio 15, VS1717 and VS 2019 in the same machine

launching the batchup file (with administrator rights) result is :

Start Generator: [NONE], char MultiByte build, cores: 8
Start build: 9:57:50,49
Failed with error #4, at 9:57:50,61 ***

windows reports are:

Failed with error #4.

If I create the directory build_master_x64 result is

CMake Error: The source directory "C:/Projects/TestCodeVS/VS2017/Easy-PQXX-Build-for-Windows-Visual-Studio/build_master_x64" does not appear to contain CMakeLists.txt.

I'm not skilled with cmake... can you help ?
