Hi, I'm a user of cmdline with CMake.

I think, those source file and executables are test project. Then, I'd suggest use CTest for it. see: https://cmake.org/Wiki/CMake/Testing_With_CTest

And, this pull-requested CMakeLists.txt is not useful for CMake users. Because, cmdline is header-only library project, therefore we need the below cmake install command:

install( FILES cmdline.h DESTINATION include )

Would you please include my suggests.

@tanakh I use the library with CMake ExternalProject. But, In currently, we need a little trciks:

ExternalProject_Add( external_cmdline
  GIT_REPOSITORY git@github.com:tanakh/cmdline.git
  PREFIX            ${CMAKE_CURRENT_BINARY_DIR}/external
  # trick-1: empty configure directive
  CONFIGURE_COMMAND ""
  # trick-2: empty build directive
  BUILD_COMMAND     ""
  # trick-3: custom install command
  INSTALL_COMMAND
    COMMAND ${CMAKE_COMMAND}
      -E copy_if_different
        ${CMAKE_CURRENT_BINARY_DIR}/external/src/external_cmdline/cmdline.h
        ${CMAKE_CURRENT_BINARY_DIR}/include/cmdline.h
)

It's helpful to CMake users if you merge and add supporting CMake with this proposes.

Thank you.
