Use set_target_properties to set output attrs

Use set_target_properties to set LIBRARY_OUTPUT_DIRECTORY, ARCHIVE_OUTPUT_DIRECTORY and RUNTIME_OUTPUT_DIRECTORY, in this way, geos will not interfere output settings of users' project.

Is there a way to apply this to all of our targets without copy-paste? (benchmarks, tests, etc.)

For PDAL we have macros that roll up all of these kind of settings for the different categories of targets. See https://github.com/PDAL/PDAL/blob/master/cmake/macros.cmake for inspiration.

I think it can be achived by put all targets into a variable. Maybe there's a better way.

I have done that. And I've added geos and geos_c.

If you rebase to main do we get a green CI?

This PR addresses geos_c and geos but we have many more targets for benchmarks, tests, and utilities (geosop). I would prefer not to have all of these moved.

We can add more targets into it.
