That would be the way.

You can pass input files to the `run` rule:

    run my_cmake_test.cpp : : myfile1 myfile2 ;

(https://boostorg.github.io/build/manual/develop/index.html#bbv2.builtins.testing)

If these are targets, they will refer to files in the bindir; if not, to 
source dir. Relative paths are relative to the current Jamfile.

I'm not sure if you could do

    run my_cmake_test.cpp : : my_cmake_test ;

to obtain a path to my_cmake_test.exe though. It would probably be easier to 
infer the directory corresponding to where the test executable is placed 
from argv[0] (but I haven't tried that this works.)

If not, you could perhaps use a dummy obj target

    obj cmake_test_obj : cmake_test_source.cpp ;

and then

    run my_cmake_test.cpp : : cmake_test_obj ;
