There is a way.   You can have all of the tests be independent projects.
Then use the ctest --build-and-test option.  That is what we do for cmake.

For example, there is a test in CMake that tests the custom commands,
and the ADD_TEST line looks like this:

 ADD_TEST(CustomCommand  ${CMAKE_CTEST_COMMAND}
    --build-and-test 
    "${CMake_SOURCE_DIR}/Tests/CustomCommand"
    "${CMake_BINARY_DIR}/Tests/CustomCommand"
    --build-two-config
    --build-generator ${CMAKE_TEST_GENERATOR}
    --build-project CustomCommand
    --build-makeprogram ${CMAKE_TEST_MAKEPROGRAM}
    --build-exe-dir "${CMake_BINARY_DIR}/Tests/CustomCommand/bin"
    --test-command CustomCommand
    )

What this does is runs cmake on the project CustomCommand, then builds and
runs the test.

This seems like a bug, that can be fixed.  My guess is that the config.h file
is somehow being changed.
