setlocal build errors on example plugins

[hockinsk]

I've tried every piece of advice to get rid of this error when building but nothing seems to allow visual studio to build the examples. admin/user no difference, Win11 dev mode on/off no difference. cmake will build without errors and success, but then they are not recognised as plugins by a vsthost and just fail to load when manually loading them instead.
Is there any more uptodate documentation on how to simply get from the cmake step and successfully building the vs solutuon without setlocal errors?
