Installing cpanm fails on Windows 11: make (e=2): The system cannot find the file specified.

I am trying to install cpanm on Windows 11 (see https://github.com/Perl/perl5/issues/20395 for information of how I installed perl):

>cd c:\Users\hakon\perl\test\cpan_cpanm 
# delete .cpan folder
>rmdir /S/Q c:\Users\hakon\.cpan
>where perl
C:\perl-debug\bin\perl.exe
>perl --version

The system cannot find the file specified

This issue has been resolved now. The reason why pl2bat.bat was not present, was that I had run gmake install without specifying INST_TOP. This caused the default value to be used (C:\perl) instead of the value I specified when running gmake all. See https://github.com/Perl/perl5/issues/20395 for more information.
