Review Comment:
`-j` doesn't exist in CMake 3.11 or earlier:
https://cmake.org/cmake/help/v3.11/manual/cmake.1.html
How about defining `CMAKE_BUILD_PARALLEL_LEVEL` environment variable instead?
https://cmake.org/cmake/help/latest/envvar/CMAKE_BUILD_PARALLEL_LEVEL.html#envvar:CMAKE_BUILD_PARALLEL_LEVEL
```shell
export CMAKE_BUILD_PARALLEL_LEVEL=${CMAKE_BUILD_PARALLEL_LEVEL:-$(nproc)}
cmake --build ...
```
