#
|
|
# 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
|
|
#
|
|
# USAGE:
|
|
#
|
|
# 1. Copy this file into your cmake modules path.
|
|
#
|
|
# 1. Add the following line to your CMakeLists.txt: include(CodeCoverage)
|
|
#
|
|
# 1. Append necessary compiler flags: APPEND_COVERAGE_COMPILER_FLAGS()
|
|
#
|
|
# 1. If you need to exclude additional directories from the report, specify them
|
|
# using the COVERAGE_LCOV_EXCLUDES variable before calling
|
|
# SETUP_TARGET_FOR_COVERAGE_LCOV. Example: set(COVERAGE_LCOV_EXCLUDES 'dir1/*'
|
|
# 'dir2/*')
|
|
#
|
|
# 1. Use the functions described below to create a custom make target which runs
|
|
# your test executable and produces a code coverage report.
|
|
#
|
|
# 1. Build a Debug build: cmake -DCMAKE_BUILD_TYPE=Debug .. make make
|
|
# my_coverage_target
|
|
#
|
|
|
|
include(CMakeParseArguments)
|
|
|
|
# Check prereqs
