Thanks Igor and Mariano. I synced my clone repo with blessed, and was
able to build Cog via cmake (looks like I did not read one paragraph
in Mariano's guide ;)
I ran into the cc1: error: unrecognized command line option
"-mno-fused-madd" error while compiling the float math plugin.

not very new but did not really have plans to upgrade it. I followed
commenting out the relevant line in FloatMathPlugin/CMakeLists.txt
I see where it is coming from (class CPlatformConfig in CMakeVMMaker):
"extra rules for FloatMathPlugin"
"according to http://www.netlib.org/fdlibm/readme
it should be compiled with no optimizations"
maker addDefinitions: '-O0 -mno-fused-madd'.
