Exclusions do not work for ccov-all-* targets about cmake-scripts

@ambroff I ran into a similar problem, especially considering the fact that I wanted to achieve the same report for Linux (lcov) and macOS (llvm-cov). This declaration at the very top level did the trick:

# Handle codecoverage
if(CODE_COVERAGE)
    # Now we can exclude the stuff that we aren't interested in from the tracefile:
    # 1) system deps; 2) tests; 3) build; 4) thridparty-code
    set(coverage_excludes EXCLUDE
        "/usr/*" "build/*" "*/build/*" "tests/*" "*/tests/*" "external/*" "*/external/*")
    add_code_coverage_all_targets(${coverage_excludes})
endif()

Then for every target I want code coverage I declare something like this:

# Add definition for foobar library.
add_library(foobar STATIC
    foobar.cpp
    another.cpp)

# ...

if(CODE_COVERAGE)
    target_code_coverage(foobar AUTO ALL)
endif()

N.B. To declare exclusion you have use globbing, not regular expressions.

I think this one can be closed due to the lack of any reaction.
