Use cmake.exe from path, if it is found there

[tksuoran]

This change makes configure.bat to use cmake.exe from path, if it is found there. This makes the script to work on systems that have Visual Studio installed, but no separate installation for CMake for Windows. Opening Developer Command Prompt for VS 2022 brings cmake bundled with Visual Studio into path.

I am not proficient with bat scripts, so someone else should verify this is a good change. It works on my machine, but I've only tested the path where cmake.exe is found from path.

Oh that's interesting !
Does it mean that VSCode's bundled CMake can compile geogram ? (last time I tried it did not work, it did not support some CMake functions that geogram is using, but it was long time ago).

Works for me:

C:\git\tksuoran\geogram>where cmake
C:\Program Files\Microsoft Visual Studio\2022\Professional\Common7\IDE\CommonExtensions\Microsoft\CMake\CMake\bin\cmake.exe

C:\git\tksuoran\geogram>cmake --version
cmake version 3.29.5-msvc4

CMake suite maintained and supported by Kitware (kitware.com/cmake).

C:\git\tksuoran\geogram>configure.bat
