[Bf-committers] Cmake and CMakeCache.txt questions

[W. Nelson]

Multiple instructions say do a cmake-gui ../blender and then a make from inside the build folder.  So: 

Does "make" from inside the build folder use the build folder CMakeCache.txt or does it use the ../blender/CMakeCache.txt?   
    
Also, inversely, if you do a "make" from inside the /blender folder does it use that CMakeCache.txt file or the one in ../build?  I see that it sets up the build folder and uses it for an out of source build.

When you do an update of the source files and do either of these makes, are your settings lost to a new CMakeCache.txt file that was just downloaded?

What is the best way to manage multiple CMakeCache.txt files for multiple types of builds in the same out of source build folder?

Thanks for the clarifications.  They will help save a lot of time experimenting and digging through the scripts.
