* 3 funcs needed for some mwcc compilers
* some PR feedback
* lots more via pair programming with Simon
* cleanup, add test dir as an include dir for tests
* bugfix
* Fix cmake install command
PROGRAMS specifies executable files, while TARGETS specifies cmake
targets. This install command happened to work when doing an in-tree
build (build dir == source dir) but will otherwise fail.
* Explicitly link std::filesystem as needed
On some older compilers, std::filesystem is provided as a separate
library from the C++ standard library. For example, on GCC 8, one must
explicitly link with -lstdc++fs.
We can use a drop-in https://github.com/vector-of-bool/CMakeCM module to
automate detection of and linking against this auxiliary library when needed.
* Add missing include
std::min is in <algorithm> header
This is transitively included in libstdc++ (GCC)
but not in libc++ (Clang)
(Encountered when testing -lc++fs auxiliary library linking in Clang 7)
