[cmake] Use source-groups in Polly

Authored by ctetreau on Jan 2 2020, 3:56 PM.


  • Configure CMake to setup source-groups for Polly. Source groups

describe how source files should be organized in IDEs. By default, all
headers are dumped into one folder under PollyCore and all source files
into another. On disk, these files are organized into folders, but this
isn't reflected in the IDE. This change uses CMake source groups to have
the IDE reflect the on disk layout. This will make it easier to visualize
the project structure for users of Visual Studio and XCode

This looks reasonable from my side.

Why not using GLOB_RECURSE such that setup_polly_source_groups_helper does not need to call itself?

Suppose we have this directory structure:

|       |-------inner
|-a.cpp |-c.cpp |-e.cpp
|-b.cpp |-d.cpp |-f.cpp

file with GLOB_RECURSE would return a list similar to this:

[ root\outer\inner\e.cpp, root\outer\inner\f.cpp, root\outer\c.cpp, root\outer\d.cpp, root\a.cpp, root\b.cpp ]

However, if we were to pass this list to source_group, we'd be in the same situation that we started in. What we need to do is to have three lists:

[ root\outer\inner\e.cpp, root\outer\inner\f.cpp ]
[ root\outer\c.cpp, root\outer\d.cpp ]
[ root\a.cpp, root\b.cpp ]

We also need three calls to source_group. If ${prefix} = "src", we need:

source_group("src\\outer\\inner" FILES root\outer\inner\e.cpp, root\outer\inner\f.cpp)
source_group("src\\outer" FIELS root\outer\c.cpp, root\outer\d.cpp)
source_group("src" FILES root\a.cpp, root\b.cpp)

Splitting the lists and computing the first argument to source group are the complicating factors. We could derive this information from the result of the recursive glob, that wouldn't be any simpler than just recursing and doing the non-recursive glob.
