For static libraries the macro GENERATE_EXPORT_HEADER produce an output
like this one:
...
#else
# ifndef CTEST_EXPORT
# ifdef cTest_EXPORTS
/* We are building this library */
# define CTEST_EXPORT
# else
/* We are using this library */
# define CTEST_EXPORT
# endif
# endif
...
For for a static version of a library CTEST_EXPORT is empty.
For Windows and the MSVC it is not always a good idea, since the MSVC
can produce errors in this case.
So I propose (static versions of libraries): For the MSVC and Windows
CTEST_EXPORT should be defined with "extern", either by option or by
default.
