Set ENABLE_COVERAGE=ON to enable code coverage testing.
After the build is finished, run 'make coverage' to run the unit tests
and generate a code coverage page in the ${CMAKE_BINARY_DIR}/coverage
directory.
Reference: https://github.com/bilke/cmake-modules/blob/master/CodeCoverage.cmake
(commit 59f8ab8dded56b490dec388ac6ad449318de8779)
CMakeLists.txt:
- Moved the CMAKE_BUILD_TYPE check to before INCLUDE(CTest),
and capitalized the 'D' in "Debug", since CodeCoverage.cmake
checks for that.
gcc.cmake:
- Set the required CFLAGS. (These aren't checked for explicitly, since
they're basically present on all gcc since forever.)
- Link all targets to -lgcov.
- Create a 'coverage' target for automatically running tests and
generating HTML output using lcov/genhtml.
options.cmake:
- Added ENABLE_COVERAGE.
scripts/lcov.sh:
- Shell script used by the 'coverage' target to generate the lcov/genhtml
output from the gcov profiling data.
