I don't understand the problem.
When I try to install somewhere, where I'm not allowed to write the install 
fails:
CMake Error: Error in cmake code at
/home/alex/src/tests/envvarininstall/cmake_install.cmake:35:
FILE cannot create directory: /usr/usr/local/share/foo. Maybe need 
administrative privileges.

Or do you mean the directory is writeable for the developer, but he doesn't 
have write permission for the file ?
