From cmake itself:
```
Note We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate. The CONFIGURE_DEPENDS flag may not work reliably on all generators, or if a new generator is added in the future that cannot support it, projects using it will be stuck. Even if CONFIGURE_DEPENDS works reliably, there is still a cost to perform the check on every rebuild.
```
A standard template shouldn't even consider using glob.
* enforce standards conformance on MSVC
* add \W4 flag for test compilation
* enable compiler warnings for the library target when building tests
* update note on testing frameworks
* turns out only clang understands strongly typed enums
