jan iversen commented on COR-22:
--------------------------------

I can see your point, but I definitively don´t want our build system to be depending on environment variables like PROJECT_PATH. 

In my tree I have "externals" (which are filled once with your scripts) and "build" as the only non-git directories, I don´t feel that disturbing, but I am also not against your idea if it can be solved without environment variables.

"build" is only in the tree due to my choice.

> When building from the source, all transient data, including downloads of externals, should happen separate from the source-code repository working copy.
> The repository working copy may be in a location that is not suitable for writing.  It may also be a performance bottleneck to use the same location as the working repository for transient build-related material.  There may also be storage-limitation considerations.
> Ideally, a build directory can be created anywhere and all build activities conduction in that location, separate from the source-code repository.  One complication is any downloading of external sources and libraries, and how those can be included in any build of the source tree.
