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.
