I am running into an issue that causing me a bit of trouble:
file(GLOB globOutput test)
returns the absolute path to test (assuming there is a test directory
under my current dir). Whereas
file(GLOB globOutput .)
returns an empty string. This is particularly annoying because
file(GLOB globOutput non-existant-dir)
also returns an empty string.
And the follow on to this is that the documentation for IS_DIRECTORY,
EXISTS, ... says:
Behavior is well-defined only for full paths.
What exactly does that mean? Just to clarify, is a "full path" an
absolute path (e.g. as determined by IS_ABSOLUTE)? The only way I have
found to get an absolute path is to use file(GLOB which works for
anything other than .

I'd suggest not using file(GLOB in general, and especially for this
purpose or for creating lists of source files.
If you want to know the directories involved in the build, use:
* CMAKE_SOURCE_DIR
o
http://cmake.org/cmake/help/cmake-2-8-docs.html#variable:CMAKE_SOURCE_DIR
* CMAKE_BINARY_DIR
o
http://cmake.org/cmake/help/cmake-2-8-docs.html#variable:CMAKE_BINARY_DIR
* CMAKE_CURRENT_SOURCE_DIR
o
http://cmake.org/cmake/help/cmake-2-8-docs.html#variable:CMAKE_CURRENT_SOURCE_DIR
* CMAKE_CURRENT_BINARY_DIR
o
http://cmake.org/cmake/help/cmake-2-8-docs.html#variable:CMAKE_CURRENT_BINARY_DIR
To get an absolute path, do the following:
get_filename_component(outputvar "somedir" ABSOLUTE)
http://cmake.org/cmake/help/cmake-2-8-docs.html#command:get_filename_component
Hope this helps!
