How to print WORKING_DIRECTORY in CMake?

I have this line in my CMakeLists.txt:

add_test(NAME ${PROJECT_NAME} COMMAND ${PROJECT_NAME} WORKING_DIRECTORY ${PROJECT_SOURCE_DIR})

The problem is that WORKING_DIRECTORY does not seem to be set correctly.

message("Futurama ${PROJECT_SOURCE_DIR}")

It shows that PROJECT_SOURCE_DIR is what I expect, but when I run my generated VS projects, the work folder is $(ProjectDir), and that is wrong since I do the build in a separate folder.

Is it possible that setting of WORKING_DIRECTORY is broken for the Visual Studio generator?

If not, how can I print the status of WORKING_DIRECTORY after add_test?

ctest cmake visual-studio

There are a few ways you may verify that the WORKING_DIRECTORY is set properly.

Programmatically (as commented):

get_test_property(${PROJECT_NAME} WORKING_DIRECTORY test_dir)
message("My test's working directory: ${test_dir}")

Inspection:

Navigate to the CTestTestfile.cmake file in your build folder, and open it in a text editor. You can see in the commands here that the WORKING_DIRECTORY property is being properly set.

However, the $(ProjectDir) listed for Working Directory of the RUN_TESTS Visual Studio project is pointing to a folder in your build directory; this is a Debugging property and isn't actually used when running the CTest tests. This is used when Visual Studio is debugging an executable. Because the RUN_TESTS project cannot actually be debugged (the CTest tests are actually run as a post-build event), this Working Directory property doesn't apply to your situation.
