The `-g` option should be removed because it is handled via the `CMAKE_BUILD_TYPE` variable.

@bluca Could we update CMake minimum required version to 3.6 or higher? Many [distributions](https://repology.org/badge/vertical-allrepos/cmake.svg?minversion=3.6) have a higher version as 3.6. This version will allow use to use the `IMPORTED_TARGET` argument...

The list of not supported distributions between [3.0](https://repology.org/badge/vertical-allrepos/cmake.svg?minversion=3.0) and [3.5](https://repology.org/badge/vertical-allrepos/cmake.svg?minversion=3.5) isn't that big. The [3.6](https://repology.org/badge/vertical-allrepos/cmake.svg?minversion=3.6) is a problem and CentOS is restricted to 2.8.12. We have to check the code...

Do you mean we should fix the issue only for newer CMake versions and otherwise fall back to the current behaviour?

The pull request #456 adds support for the Structurizr !include directive. Any feedback will be greatly appreciated.
