Summary:                    Support for link time optimization for recent GCC
compilers
Description: 
Hello!

I tried to play with INTERPROCEDURAL_OPTIMIZATION on cmake 3.4.2 but found it's
not working really well.

After short grep'ing over source I have found there are not support for this
option for non Intel compilers.

So I could like to ask for LTO support for cmake for GCC compiler.  Recent GCC
compilers do very-very big amount of code optimization and it's very important
to have this option in project build system.

Thanks a lot!
