googletest, POWERSHELL_PATH-NOTFOUND and other errors on Linux

[expenses]

Here's what happens when I try and build this on Arch Linux:
cmake -S . -B build -G Ninja; and cmake --build build:

The powershell issue can be worked around by installing the powershell-bin AUR package. I'm not sure why I should need to install a special shell to build a SDK like this, but whatever. I then commented out the gtest stuff and tried to build it again:
