CMake progress report

At the moment, we're down to the following libraries
missing CMake support on develop:

asio
locale
log
numeric/odeint
numeric/ublas
parameter_python
python
sync

I've asked Chris how we can proceed with adding a
CMakeLists.txt file to ASIO so that we can unblock
Log (and Beast.)

In addition, the following libraries are currently
disabled as having incompatible CMakeLists.txt
files in their root directories:

beast
callable_traits
compute
gil
hana
hof
safe_numerics
static_string
stl_interfaces
yap

I'm working on documenting the CMake support
infrastructure, but I'm not done yet.
