configure directory is different with install directory issue

[qubitpercy]

My configuration command is:

../configure --prefix=/home/username/project/ProjectName/install/dir/be --enable-misaligned --enable-commitlog --enable-dual-endian --without-boost --without-boost-asio --without-boost-regex

And I've checked configure log. The location I configured is /home/username/project/ProjectName/install/dir/be. However, whenever I install the spike, it will go to /home/username/project/ProjectName/install/ which is up up directory of my configuration.
