Summary

0015683: Extend --trace to --coverage mode for detection of "dead" cmake code

Description

my intention is to find "dead" cmake script code in the project for cleanup and maintainance of the scripts.

I have adapted the gcovr script to parse the cmake script output in --trace mode to detected "code coverage" and write text or html output. Results attached below.

No i have some issues:

- The trace mode does report multi line statements as "one line" statement.
This should be reported as RANGE (e.g. not with just one line number, with start and end line number (e.g. filename(3:5): )

- the commands closing are not considered in trace output. so to each if(), macro() or other commands, the enclosing endif(), endmacro() etc are not "covered". This should be also traced or covered

For complete finalisation is must reload the file and mark the commented and blank lines as "covered". But thats ok for me for the covering issues.

So my suggestion would be to extend the trace mode or create an additional coverage mode.

Steps To Reproduce

cmake with --trace output activated and multiline statements like

set( MY_VAR
     test.cpp
     test.h
     ...
)

if( WIN32 )
  set( MYVAR2 )
endif()

Additional Information

The attached files are sample output from the adapted gcovr script.
Script cant be published cause i have to clarify the copyright issues with the "original" script holders.
