Jarryd Beck	848880d931	Fix arguments after -- without declared positional Fixes #36. This fixes handling arguments passed after `--` when no positional arguments have been declared, or when the positional arguments have all been used up. The bug was that the extra arguments were lost. Now they are retained in the modified argv.	2017-05-06 14:16:00 +10:00

Mario Badr	e005d07656	Use cmake interface library Fixes #33. This PR uses cmake's interface library feature: An INTERFACE library target does not directly create build output, though it may have properties set on it and it may be installed, exported and imported. This makes it easier to include the header only library in a cmake project. After using add_subdirectory on the cxxopts directory, one simply needs to include cxxopts in their target_link_libraries, which will allow the user's target to inherit the properties of the cxxopts header library (see changes to example and test).	2016-12-03 07:50:14 +11:00
