with `REL_INV_INSTALL_PATH(FILE VARIABLE)` to compute the relative
inverse install path of `FILE` and store it into `VARIABLE`
eg:
```
rel_inv_install_path("${CMAKE_INSTALL_LIBDIR}/pkgconfig" _PC_REL_INV_INSTALL_PATH)
set(_PKG_CONFIG_PREFIX "\${pcfiledir}/${_PC_REL_INV_INSTALL_PATH}")
```
and `LIB_REL_RPATH(TARGET_INSTALL_DIR VARIABLE)` to compute the relative
path from this `TARGET_INSTALL_DIR` to `CMAKE_INSTALL_LIBDIR`."
eg:
```
set(${PYWRAP}_INSTALL_DIR ${PYTHON_SITELIB}/${PROJECT_NAME})
if(UNIX)
lib_rel_rpath(${${PYWRAP}_INSTALL_DIR} ${PYWRAP}_INSTALL_RPATH)
set_target_properties(${PYWRAP} PROPERTIES INSTALL_RPATH "${${PYWRAP}_INSTALL_RPATH}")
endif()
install(TARGETS ${PYWRAP} DESTINATION ${${PYWRAP}_INSTALL_DIR})
```
