From 6b60df806daef288a1143822677c8497f56958de Mon Sep 17 00:00:00 2001 From: Scott Murray Date: Fri, 18 Sep 2020 15:51:14 -0400 Subject: Add source and coverage information to widgets Add source and coverage information installation to debug and coverage widgets. The source tree will be installed to "src" in debug and coverage widgets, with some non-source directories like doc/docs excluded. The gcc produced "gcno" files for generating coverage reports will be installed to "coverage" in coverage widgets. A different directory than that for source is used, as the gcno files are in the build output hierarchy, which is not the same as the source tree hierarchy when using CMake. This hierarchy needs to be preserved to be able to use gcc's coverage support. As part of this scheme, an environment file containing values for the GCOV_PREFIX and GCOV_PREFIX_STRIP variables is generated and added to "coverage". The latter variable can only be calculated during widget build, and is essential for abstracting the build directory location and enabling gcov usage on target.
