+- cannot make packages like import myproj.simulation. It replaces "." with "_"
+- most of the case, check following

+- `${SKBUILD_PLATLIB_DIR}`: The original platlib directory. Anything here goes
+  directly to site-packages when a wheel is installed.
+- `${SKBUILD_DATA_DIR}`: The data directory. Anything here goes to the root of
+  the environment when a wheel is installed (use with care).
+- `${SKBUILD_HEADERS_DIR}`: The header directory. Anything in here gets
+  installed to Python's header directory.
+- `${SKBUILD_SCRIPTS_DIR}`: The scripts directory. Anything placed in here will
+  go to `bin` (Unix) or `Scripts` (Windows).
+- `${SKBUILD_METADATA_DIR}`: The dist-info directory. Licenses go in the
+  `licenses` subdirectory. _Note that CMake is not run in the
+  `prepare_metadata_\*` hooks, so anything written to this directory will only
+  be present when writing wheels.\_
+- `${SKBUILD_NULL_DIR}`: Anything installed here will not be placed in the
+  wheel.
