Summary0012223: Support of linked resources in Eclipse/CDT (single files, not folders)
DescriptionWhen you´d like to add a single file that is placed outside the regular source folder, you can use the "linked resource" function of Eclipse/CDT.
Using this you will get a link to a single file within your project, that can be edited, compiled, etc. as if it was in your source folder.

At the moment it (seems that it(?)) isn´t possible to create links when using CMake to create a Eclipse project. The files will be compiled, as they should, but you won´t be able to see them in the Eclipse project explorer.
Steps To Reproducee.g. add_library( foo A_FILE_OUTSIDE_OF_THE_REGULAR_SOURCE_FOLDER)

cmake -G "Eclipse CDT4 - Unix Makefiles"

 Indeed.
How should this be done ?
I could add special variables like CMAKE_ECLIPSE_LINKED_FOLDERS, which you could set to a list of folders for which linked resources are created.
Or more general a list of files or directories for which linked resources are created.

But maybe we can reuse something which already exists in cmake.
How about using the source_group() command for this in Eclipse ?
http://www.cmake.org/cmake/help/cmake-2-8-docs.html#command:source_group [^]

So you could say
source_group(MyFavouriteFiles FILES abc.c foo.c bar.c)

and it would create a virtual folder named "MyFavouriteFiles" which contains links to the listed files.

What do you think ?

 Well,

at the moment our linked files look like this in the .project file:

<linkedResources>
    <link>
    <name>Foobar.cpp</name>
        <type>1</type>
    <location>../foo/Foobar.cpp</location>
    </link>
    <link>
        ...
    </link>
</linkedResources>

So, there are no extra folders for the linked files. However, I think that there are many people, who prefer to have those files grouped also.

So what about something like:
CMAKE_ECLIPSE_LINKED_FILES where you may list all files:
set( CMAKE_ECLIPSE_LINKED_FILES ../foo1/bar1.cpp ../foo2/bar2.cpp ../foo2/bar3.cpp)

and a second one CMAKE_ECLIPSE_LINKED_FILES_FOLDER:
set( CMAKE_ECLIPSE_LINKED_FOLDERS folder_for_my_linked_files )

This one could create those linked resources at top level if not set and otherwise a folder, where the linked files will be found in?

Grouped folders won´t work, because if there are files in the same folder, that don´t belong to the project, you will see them within your project. At least, you can something similar to this with out-of-source-builds already.

I don´t know if this is acceptable for you or fits to the concept cmake follows, but if so, I would prefer something that works in this way.

Anyway, I would be happy about everything that makes it possible to link single files and see them in the eclipse project explorer. :-)

wAy

 The generated project now contains a virtual folder [Targets], where each target is again a sub-virtual folder, which contains links to all its source files, no matter where they are located.

This is now in the "next" branch of cmake.
Please give it a try and let me know if something doesn't work.
