This upgrade uncovered two issues:
ntcore wasn't forcing C++17, which caused a linker error with googletest
Matcher symbols:
```
undefined reference to `testing::Matcher<std::basic_string_view<char, std::char_traits<char> > >::Matcher(std::basic_string_view<char, std::char_traits<char> >)'
```
test_span.cpp wasn't including <algorithm> to use std::sort() and
std::is_sorted().
The CMake enable/disable flags as currently structured are a confusing mix of
WITH, WITHOUT, and USE with odd defaults. This changes the flags to consistently
use WITH and default the build options to everything enabled.
- Build both debug and release binaries
- Append "d" to debug libraries in the style of opencv
- Split shared and static classifiers
- Add raspbian support
