[CMake] Using source_group in projects with sub directories

[Dominik Rausch]

Hi

 

We currently have a project with multiple subdirectories, and want to use a
structure where the top-level CmakeLists.txt only needs to know its subdirs,
and not what files/subdirs/sourcegroups are defined in these subfolders. The
CmakeList.txt’s would look something like this

 

Top-level cmake  file

 

set( dirFiles a.h   a.cpp )

set( allFiles ${dirFiles} )

source_group( "sourcegroup" FILES ${dirFiles} )

add_subdirectory( subdir )

add_library( MyLib ${allFiles} )

 

set( relDir "subdir" )

Subdir cmake file

 

set(localFiles  b.h   b.cpp)

 

foreach( file ${localFiles} )

    list( APPEND localFullDirFiles "${relDir}/${file}" )

    list( APPEND allFiles "${relDir}/${file}" )

endforeach( file )

 

source_group( "anothersourcegroup" FILES localFiles )

 

set( allFiles ${allFiles} PARENT_SCOPE )

 

However, in this case the files from the subdir are not affected by the
subgroup (neither are they if they are written relative to the subdir, i.e.
without the relDir prefix).

Is it necessary to use the source_group command in the same file as the
add_library command? Or is there any other way to get it working?

 

Regards and Thanks

  Dominik
