# ECMCoverageOption

Allow users to easily enable GCov code coverage support.

Code coverage allows you to check how much of your codebase is covered by your tests. This module makes it easy to build with support for GCov.

When this module is included, a `BUILD_COVERAGE` option is added (default `OFF`). Turning this option on enables GCC’s coverage instrumentation, and links against `libgcov`. On Clang, the option enables coverage compatible with GCC using –coverage.

Clang support was added on version 6.29.

Since 1.3.0.
