cmake: Split math_opt into sub library

XCode do not support object library with several file with the same name
since it use a flat directory, Xcode "fix" using a UID but CMake can't catch it.

math_opt also use a parameters.proto which conflict with the
glop/parameters.proto -> need to split the proto to .cc generation in
two libraries
