The closest I've come to solving this problem is that for each test
${testTarget}, I add two cmake tests:
add_test(NAME build_${testTarget} COMMAND ${CMAKE_COMMAND} --build
"${CMAKE_BINARY_DIR}" --target ${testTarget} --config
$<CONFIGURATION>)
add_test(NAME someName COMMAND ${testTarget} ...)
It might even be possible to combine them into one command, perhaps
with a custom test driver.
