Summary0011153: cmake out of source build writes build files at source dirs
Description I discovered than in the special case of a substituted PROJECT_SOURCE_DIR,
all build files for subdir packages are created in PROJECT_SOURCE_DIR and not at the PROJECT_BINARY_DIR.

I use windows XP cmd shell
     subst w: z:/some/deep/path/to/source/dir

Than I create a new build dir:

cd /d w:/
mkdir build
cd build
cmake ..

after that, all subdirs of the source dir are created as
filled with the cmake build files.

I tested cmake 2.8.0, 2.8.1 and 2.8.2 version. all have the same behaviour!
The created project builds fine too.

It seems that the PROJECT_BINARY_DIR and the subdir paths are concatenated without a path separator.
TagsNo tags attached.

Does CMake 2.8.3 have the same issue?

Did Brad's referenced commit in the previous note fix this?

Is this still an issue?

Yes this is still an issue, tested with CMake 2.8.3 on Windows XP

Hmm, sounds like cmake does not like the subst command. I am not even sure how one would add support for something like that...

This has nothing to do with "subst" per se, and everything to do with the combination of: a CMakeLists.txt at the root of a Windows drive letter, and add_subdirectory calls in that CMakeLists file.

Easily reproducible with putting a CMake-based source tree at the root of any Windows drive...

The easy workaround, of course, is to put your source tree in a directory named "s" and map it such that the full path to the source tree is "w:/s"

That should avoid the problem. (At least, it did for me, when I backed up one level on the subst-ing...)

Unsetting the target version field. Since there is an easy workaround, and plenty of other more important bugs to try to finish for the 2.8.4 release, this one is: deferred until later.
