# Optional:
# PUBLIC - Sets the visibility for added compile options to targets to PUBLIC instead of the default of PRIVATE.
# INTERFACE - Sets the visibility for added compile options to targets to INTERFACE instead of the default of PRIVATE.
# PLAIN - Do not set any target visibility (backward compatibility with old cmake projects)
# AUTO - Adds the target to the 'ccov' target so that it can be run in a batch with others easily. Effective on executable targets.
# ALL - Adds the target to the 'ccov-all' and 'ccov-all-report' targets, which merge several executable targets coverage data to a single report. Effective on executable targets.
# EXTERNAL - For GCC's lcov, allows the profiling of 'external' files from the processing directory
