Summary0013358: Error importing generated Eclipse project with LIBRARY_OUTPUT_PATH set to ${CMAKE_CURRENT_BINARY_DIR}
DescriptionSetting LIBRARY_OUTPUT_PATH to the current binary directory in a CMakeLists.txt and using it with the "Eclipse CDT4 - MinGW Makefiles" generator creates an Eclipse project that causes an error when being imported into an eclipse workspace.

Steps To Reproduce1. Create CMakeLists.txt containing these two lines:
SET (LIBRARY_OUTPUT_PATH ${CMAKE_CURRENT_BINARY_DIR})
PROJECT ( Test )

2. Use the "Eclipse CDT4 - MinGW Makefiles" generator of cmake to create an Eclipse project. It doesn't matter if an in source or out of source build is done. For example CMakeLists.txt can reside in C:\TestProject\src and the Eclipse project is created at C:\TestProject\build.

3. Import this project into an eclipse workspace.
An error message appears:
"Error processing changed links in project description file."
"Cannot create a link to C:\TestProject\build because it overlaps the locations of the project that contains the linked resource."
Additional InformationAfter removing the line that sets LIBRARY_OUTPUT_PATH the generated project can be imported without errors.

Fortunately eclipse imports the generated project despite of the error message. It's just quite annoying.

Interesting.
There is the function cmExtraEclipseCDT4Generator::AppendOutLinkedResource(), which handles those output directories.
If EXECUTABLE_OUTPUT_PATH is a subdir of CMAKE_BINARY_DIR, it does nothing.
In all other case, it seems Eclipse (at least Juno) complains that this is a bad location for a linked resource.
Maybe I should simply delete this code ?
I just tried with Eclipse Europa (3.3), and this old version also complains.
Has this ever worked ?
This is quite old code from 2007 or so.

The note above was a bit too broad.
Can you give the branch EclipseFixBadLinkedResources on cmake stage a try ?

I merged the branch into next, maybe it still makes it into 2.8.9, otherwise it will be 2.8.10.
