I´m trying to run packet generator within a VS project, it crashes while compiling because of the use of absolute path on installation from Targets and Files.

```
 ABSOLUTE path INSTALL DESTINATION forbidden (by caller): ...

```

I checked twice and all installation directories are relative. I set quite a lot of variables as sub-folders of ${PROJECT\_BINARY\_DIR} (which should be relative) such as:

```
set(INSTALL_DIR ${PROJECT_BINARY_DIR}/bin)
set(LIB_DIR ${PROJECT_BINARY_DIR}/bin/lib)
set(EXT_DIR ${PROJECT_BINARY_DIR}/bin/ext)
...

```

does CMAKE/CPACK interpret those variables as absolute paths?
If so, is there a way to make CPack working properly with those variables?
How do I use CPack when sub-relative path are involved?

thanks
