PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/572
- HAL Devicehandlers: Periodic printout is run-time configurable now
- `oneShotAction` flag in the `TestTask` class is not static anymore
- Major update for version handling, using `git describe` to fetch version information with git.
PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/601
- Add helper functions provided by [`cmake-modules`](https://github.com/bilke/cmake-modules)
manually now. Those should not change too often and only a small subset is needed
- Separate folder for easier update and for distinction
- LICENSE file included
- use `int` for version numbers to allow unset or uninitialized version
- Initialize Version object with numbers set to -1
- Instead of hardcoding the git hash, it is now retrieved from git
- `Version` now allows specifying additional version information like the git SHA1 hash and the
versions since the last tag
- Additional information is set to the last part of the git describe output for `FSFW_VERSION` now.
- Version still need to be hand-updated if the FSFW is not included as a submodule for now.
- IPC Message Queue Handling: Allow passing an optional `MqArgs` argument into the MessageQueue
creation call. It allows passing context information and an arbitrary user argument into
the message queue. Also streamlined and simplified `MessageQueue` implementation for all OSALs

- Added generic PUS TC Scheduler Service 11. It depends on the new added Emebeded Template Library
(ETL) dependency.

- Added ETL dependency and improved library dependency management
PR: https://egit.irs.uni-stuttgart.de/fsfw/fsfw/pulls/592

#
# CHANGES:
#
# 2012-01-31, Lars Bilke
# - Enable Code Coverage
#
# 2013-09-17, Joakim Söderberg
# - Added support for Clang.
# - Some additional usage instructions.
#
# 2016-02-03, Lars Bilke
# - Refactored functions to use named parameters
#
# 2017-06-02, Lars Bilke
# - Merged with modified version from github.com/ufz/ogs
#
# 2019-05-06, Anatolii Kurotych
# - Remove unnecessary --coverage flag
#
# 2019-12-13, FeRD (Frank Dana)
# - Deprecate COVERAGE_LCOVR_EXCLUDES and COVERAGE_GCOVR_EXCLUDES lists in favor
# of tool-agnostic COVERAGE_EXCLUDES variable, or EXCLUDE setup arguments.
# - CMake 3.4+: All excludes can be specified relative to BASE_DIRECTORY
# - All setup functions: accept BASE_DIRECTORY, EXCLUDE list
# - Set lcov basedir with -b argument
# - Add automatic --demangle-cpp in lcovr, if 'c++filt' is available (can be
# overridden with NO_DEMANGLE option in setup_target_for_coverage_lcovr().)
# - Delete output dir, .info file on 'make clean'
# - Remove Python detection, since version mismatches will break gcovr
# - Minor cleanup (lowercase function names, update examples...)
#
# 2019-12-19, FeRD (Frank Dana)
# - Rename Lcov outputs, make filtered file canonical, fix cleanup for targets
#
# 2020-01-19, Bob Apthorpe
# - Added gfortran support
#
# 2020-02-17, FeRD (Frank Dana)
# - Make all add_custom_target()s VERBATIM to auto-escape wildcard characters
# in EXCLUDEs, and remove manual escaping from gcovr targets
#
# 2021-01-19, Robin Mueller
# - Add CODE_COVERAGE_VERBOSE option which will allow to print out commands which are run
# - Added the option for users to set the GCOVR_ADDITIONAL_ARGS variable to supply additional
# flags to the gcovr command
#
# 2020-05-04, Mihchael Davis
# - Add -fprofile-abs-path to make gcno files contain absolute paths
# - Fix BASE_DIRECTORY not working when defined
# - Change BYPRODUCT from folder to index.html to stop ninja from complaining about double defines
#
# 2021-05-10, Martin Stump
# - Check if the generator is multi-config before warning about non-Debug builds
#
# 2022-02-22, Marko Wehle
# - Change gcovr output from -o <filename> for --xml <filename> and --html <filename> output respectively.
# This will allow for Multiple Output Formats at the same time by making use of GCOVR_ADDITIONAL_ARGS, e.g. GCOVR_ADDITIONAL_ARGS "--txt".
#
# USAGE:
#
# 1. Copy this file into your cmake modules path.
#
# 2. Add the following line to your CMakeLists.txt (best inside an if-condition
# using a CMake option() to enable it just optionally):
# include(CodeCoverage)
#
# 3. Append necessary compiler flags for all supported source files:
# append_coverage_compiler_flags()
# Or for specific target:
# append_coverage_compiler_flags_to_target(YOUR_TARGET_NAME)
#
# 3.a (OPTIONAL) Set appropriate optimization flags, e.g. -O0, -O1 or -Og
#
# 4. If you need to exclude additional directories from the report, specify them
# using full paths in the COVERAGE_EXCLUDES variable before calling
# setup_target_for_coverage_*().
# Example:
# set(COVERAGE_EXCLUDES
# '${PROJECT_SOURCE_DIR}/src/dir1/*'
# '/path/to/my/src/dir2/*')
# Or, use the EXCLUDE argument to setup_target_for_coverage_*().
# Example:
# setup_target_for_coverage_lcov(
# NAME coverage
# EXECUTABLE testrunner
# EXCLUDE "${PROJECT_SOURCE_DIR}/src/dir1/*" "/path/to/my/src/dir2/*")
#
# 4.a NOTE: With CMake 3.4+, COVERAGE_EXCLUDES or EXCLUDE can also be set
# relative to the BASE_DIRECTORY (default: PROJECT_SOURCE_DIR)
# Example:
# set(COVERAGE_EXCLUDES "dir1/*")
# setup_target_for_coverage_gcovr_html(
# NAME coverage
# EXECUTABLE testrunner
# BASE_DIRECTORY "${PROJECT_SOURCE_DIR}/src"
# EXCLUDE "dir2/*")
#
# 5. Use the functions described below to create a custom make target which
# runs your test executable and produces a code coverage report.
#
# 6. Build a Debug build:
# cmake -DCMAKE_BUILD_TYPE=Debug ..
# make
# make my_coverage_target
#
