[CMake] CTest: Glob files to include in coverage report with 0% line coverage

[Andreas Schuh]

I am not sure where I found info on this variable, but the ITK/VTK
projects are always a good resource on the latest trends/development
in CMake/CTest/CPack.

Further, for anyone interested, please note the difference in
CTEST_EXTRA_COVERAGE_GLOB, which lists glob expressions as used by
file (GLOB), and CTEST_CUSTOM_COVERAGE_EXCLUDE, which uses regular
expressions. In the beginning, I wasn't very clear about this, but in
either case you would need to use "/test/*" or "/test/.*",
respectively, to include/exclude all files in some "test/" directory.


Regarding this variable, I was eventually looking at the source code
and figured that indeed only source files in the source tree are
considered.
