Do not call install_name_tool for Marble library

Here on my Mac I had an issue that took a long time to understand.
The build.sh script was correctly creating Marble but did not
correctly run otool on it. So I fixed this by fixing CMake for
the marble library which means we don't need to worry about it
in the build script anymore.
