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.
> Do not use within-repository folders for any build-related activity

> Key: COR-22
> URL: https://issues.apache.org/jira/browse/COR-22
> Project: Corinthia
> Issue Type: Improvement
> Environment: All
> Reporter: Dennis E. Hamilton
> Labels: building, cmake, external-resources
>
> 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.
