Update BUILDING.md

!. ATL/MFC components (v14.22) are not included by default in the C++ development kit, but are needed to compile the project.

2. In Windows (not checked for Linux distributions), cmake will build a Debug version of the software. Since cmake will check for information marked as "Release" to install the application by default (and not Debug), I think that it is fair to explicitly tell the persons who only want to install the project to build a "Release" version of the software.
