Weird. I just did a fresh install of Slic3r's 5.24.1 (64bit). It didn't have cpanm. However, I ran cpan, and within the cpan shell, ran install App::cpanminus, which was successful

After doing that, I can successfully find and run cpanm:

I wonder if something got corrupted in your version of Slic3r's 64-bit Strawberry Perl. You might want to try to uninstall and reinstall, then try to install the cpanm from inside the cpan client (it shouldn't make a difference... but since the steps worked for me, maybe they will for you as well).

If that doesn't work: do you need 64bit? If not, you might follow Slic3r's instructions for the standard 32-bit Strawberry, which does come with cpanm already installed. Given that Slic3r frequently mentions 5.24, and because Strawberry 5.26 changed away from dmake to gmake (which has caused some module installation problems for some people), I'd pick the "Strawberry Perl 5.24.2.1 (32bit)" installer link from Strawberry's main page.)

update: I should point out that for this test, I was on Windows 7, not Windows 10. It might cause different behavior.

update 2: If you still have difficulty, you might be able to ask on the Slic3r issues page for them to bundle cpanm with their custom 5.24.1 64bit -- actually, you might want to ask them to do that anyway, given the difficulties you've already had.
