+
+# USAGE: To enable any code coverage instrumentation/targets, the single CMake
+# option of `CODE_COVERAGE` needs to be set to 'ON', either by GUI, ccmake, or
+# on the command line.
+#
+# From this point, there are two primary methods for adding instrumentation to
+# targets: 1 - A blanket instrumentation by calling `add_code_coverage()`, where
+# all targets in that directory and all subdirectories are automatically
+# instrumented. 2 - Per-target instrumentation by calling
+# `target_code_coverage(<TARGET_NAME>)`, where the target is given and thus only
+# that target is instrumented. This applies to both libraries and executables.
+#
+# To add coverage targets, such as calling `make ccov` to generate the actual
+# coverage information for perusal or consumption, call
+# `target_code_coverage(<TARGET_NAME>)` on an *executable* target.
+#
+# Example 1: All targets instrumented
+#
+# In this case, the coverage information reported will will be that of the
+# `theLib` library target and `theExe` executable.
+#
+# 1a: Via global command
+#
+# ~~~
+# add_code_coverage() # Adds instrumentation to all targets
+#
+# add_library(theLib lib.cpp)
+#
+# add_executable(theExe main.cpp)
+# target_link_libraries(theExe PRIVATE theLib)
+# target_code_coverage(theExe) # As an executable target, adds the 'ccov-theExe' target (instrumentation already added via global anyways) for generating code coverage reports.
+# ~~~
+#
+# 1b: Via target commands
+#
+# ~~~
+# add_library(theLib lib.cpp)
+# target_code_coverage(theLib) # As a library target, adds coverage instrumentation but no targets.
+#
+# add_executable(theExe main.cpp)
+# target_link_libraries(theExe PRIVATE theLib)
+# target_code_coverage(theExe) # As an executable target, adds the 'ccov-theExe' target and instrumentation for generating code coverage reports.
+# ~~~
+#
+# Example 2: Target instrumented, but with regex pattern of files to be excluded
+# from report
+#
+# ~~~
+# add_executable(theExe main.cpp non_covered.cpp)
+# target_code_coverage(theExe EXCLUDE non_covered.cpp test/*) # As an executable target, the reports will exclude the non-covered.cpp file, and any files in a test/ folder.
+# ~~~
+#
+# Example 3: Target added to the 'ccov' and 'ccov-all' targets
+#
+# ~~~
+# add_code_coverage_all_targets(EXCLUDE test/*) # Adds the 'ccov-all' target set and sets it to exclude all files in test/ folders.
+#
+# add_executable(theExe main.cpp non_covered.cpp)
+# target_code_coverage(theExe AUTO ALL EXCLUDE non_covered.cpp test/*) # As an executable target, adds to the 'ccov' and ccov-all' targets, and the reports will exclude the non-covered.cpp file, and any files in a test/ folder.

+# 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
