I’m a newbe of the O2 software development and I need a step by step recipe in order to setup the most ‘confortable’ environment for the development of the software.
I followed the instructions to install the O2 environment with aliBuild program on a CentOS 7 machine, and I’m able to compile the latest version of the FlpSuite package ! 
But, the folder ‘alice/sw/BUILD’ disappared after the build phase and this avoids to me to run any ‘make’ commands in order to recompile modifications. (in discordance with that is reported in https://aliceo2group.github.io/quickstart/devel.html)
The source code is located in ‘alice/sw/SOURCES’, where should be pointed the location for the source of a forked package, in order to integrate the forked software with all the external dependancies ?
Probabilly there are threads or docs on those issues, but I wasn’t able to catch them…
Any suggestions are sincerly apreciated.
Thanks a lot
