This PR replaces UnitTest-cpp with Catch. Catch is downloaded
using cmake's ExternalProject_Add and installed into the
include directory as it's a header only library.

* Refactor cmake file to have GSL as an interface
CMake supports header only libraries as INTERFACE libraries. Using
interfaces libraries make is easier for users to use the library because
one just need to "link" agaisnt the library and necessary include paths,
definitions, flags... will be taken care of.
This commit creates a new interface library called GSL. It then add the
following things to the GSL library:
- compiler flags ex: (-std=c++14)
- definitions ex: _SCL_SECURE_NO_WARNINGS
- include paths ex: include/gsl
- natvis file
Another project can now have the GSL project as a git submodule and one
only need to add the two following lines to their project to use the
GSL.
add_subdirectory(GSL)
target_link_libraries(<some target> GSL)
After cmake 3.8.0 a lot of the logic can be simplified. Right now the
cmake file has an if for version checking, but when the minimun required
version is 3.8.0 one can just delete the branching and keep the simpler
version.
* Cut support for c++11
Compiling on GCC6.2 with only the c++11 flag will generate compilation
errors. For example some of the errors are related to the use of
enable_if_t which is a c++14 feature.
To avoid compilation errors this comiit removes c++11 support on linux.
* Refactor code that pulls unittest-cpp
Two minor changes:
- uses cmake to find a proper installation of git (in case user does not
have it on the path)
- checks for the CMakeLists file instead. This is needed for the build
itself and seems like a better way to do the checking
* Refactor tests so they show together on VS
This commit will make a VS geenrated project to group all tests under
GSL_tests
* Refactor tests configuration
This creates a test configuration interface and add all the previous
compiler options to that interface. compiler options are now sorted so
it is easier to find them, and also one per line, so that modifications
are easier to track from git.
* Nest "gsl" directory inside a new "include" directory.
* Cleanup the _MSC_VER conditionals a bit; use constexpr on VS2017+.
* Don't #define noexcept on non-Microsoft implementations.
* Workaround VS2017 bug in multi_span. (Also implement == and != for static_bounds_dynamic_range_t because I'm an EoP semantic soundness snob.)
Fixes#441.
whether using it from the development folder, from the installation
folder or from being copied into a project.
#include <gsl/gsl.h>
Updated headers/tests/instructions/cmake build accordingly
This PR should address https://github.com/Microsoft/GSL/issues/277 (less
the renaming of gsl itself)
