cmakebuilder does not quote the argument <install dir> in the option -DCMAKE_INSTALL_PREFIX=<install_dir> passed to cmake. This leads to problems if the project name contains spaces, because the project name appears as part of the <install dir> path. Because of the spaces cmake will then set the wrong install-dir path. Solution would be to do -DCMAKE_INSTALL_PREFIX="<install_dir>" instead.
