[CMake] Ctest executable dll/so search path

[Iosif Neitzke]

A problem long-suffered on Windows and when lacking RPATH.  Have seen
approaches where DLL dependencies are POST_BUILD
customed-command-copied-if-different into the executable directory, or
gymnastics with add_test WORKING_DIRECTORY, or setting a test's
ENVIRONMENT property.
