[CMake] building and running tests with one command

[Petr Kmoch]

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.
