API: wrong target build artifact paths

Brief Issue Summary

The path to the target´s build artifacts returned by the API do not resolve to the actual location of the artifact on the disk when the target is defined in another directory than cmake.sourceDirectory.

cmake.getLaunchTargetPath returns:
C:\work\src\incubator\buildpath\build\src\buildpath.exe
API project.codeModel.configurations[0].projects[0].targets[0].artifacts gives
C:\work\src\incubator\buildpath\build\src\src\buildpath.exe

Additional Information

Demo Project: buildpath.zip

Converting the build artifact path to an absolute path is done in different ways.

• API: https://github.com/microsoft/vscode-cmake-tools/blob/7b8f2e0a0e7eeac6b5241f2438de77f163622514/src/drivers/cmakeFileApi.ts#L481

• for cmake.getLaunchTargetPath: https://github.com/microsoft/vscode-cmake-tools/blob/7b8f2e0a0e7eeac6b5241f2438de77f163622514/src/drivers/cmakeFileApi.ts#L376

The API version includes the target's build directory whereas for the launchTargetPath only includes the top-level build directory. According to the cmake documentation the artifacts path is relative to the top-level build directory.

Start in src/drivers/cmakeFileApi.ts at the linked locations around lines 376 and 481, and compare how cmake.getLaunchTargetPath and the API convert CMake File API artifact paths. Reproduce the buildpath.zip case, then verify that project.codeModel.configurations[0].projects[0].targets[0].artifacts resolves to the actual artifact location relative to the top-level build directory.
