If you use the add_test(NAME <name> COMMAND <command>) signature you can
use generator expressions.

You could pass the executable directory as a parameter to the script:

add_test(NAME myTest COMMAND ${CMAKE_COMMAND}
-DMY_EXECUATABLE=$<TARGET_FILE:myTarget> -P my_script.cmake)

In the script use ${MY_EXECUATABLE}.

Hope this helps,
