Vladimar,
Could you please enumerate the advanced options that are missing
from boost's cmake setup so that I can start working on implementing
those options. (Cross Posting to Boost-CMake as that may become the
more appropriate place for this )
What are the equivalents in gcc to /w4, /w3, /w2, /w1? What are the
equivalents on icc, or any other compiler? What does bjam do?
http://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html
That list is pretty long...
It is easy enough to add some macros to the boost cmake files.
macro(set_warning_level warning_level)
if (MSVC)
elseif (GCC)
endif()
macro(set_warning_level warning_level)
Thanks
