OK, what I got from the documentation is that I can do something like
notfile run_cmake_self_test : @echo ;
actions echo
{
    mkdir __build__
    cd __build__
    cmake ..
    cmake --build .
}
but
1) this will create __build__ in whatever directory b2 is called from and
   require the test cmake file to be in the parent directory of the current
2) mkdir will fail if the directory already esists and the flags necessary
   to circumvent that are different on powershell (--force) and bash (-p)
I would recommend using a make target (warning untested):

make CMakeCache.txt : CMakeLists.txt : @echo ;
always CMakeCache.txt ;

actions echo
{
    cmake -S "$(>:D)" -B $(<:D)
    cmake --build "$(<:D)"
}

Note 1: The directory will be created automatically.
Note 2: Avoiding cd simplifies the path handling a lot.
Note 3: This could probably be split into two separate actions.
