[CMake] Coverage tests with gcov under Linux

[John Doe]

I don't know how your program works or how it is exec'ing other
software.  However, it should ensure that the proper environment is
set before these other programs are executed.

Using "setlocale" may result in whatever system functions and whatever
"regex" functions you are using to at least read the input in a manner
that you are expecting.

Perhaps "setlocale" is not the appropriate function, but cmake needs
to ensure whatever program's output being parsed is in the right
language.

Good luck,

Juan
