[yocto] CMake based recipes and defining CMAKE_BUILD_TYPE

[Matt Schuckmann]

Aright thank you for checking into this, you went farther then I expected. 
I will take the approach of setting it for the recipes I really care about and leave the rest alone.

Not exactly: After short build I saw:

* There are some sed on '*-noconfig.cmake' they are going to break
* libeigen fails because it supports 'Debug' and 'Release' only (and I
bet there are more)

Will skip further tests and get the feeling that a common solution won't do...
