It doesn't work for me:
[tyle...@tpb006:~/cmake-test-install-prefix]$ cmake --version
cmake version 2.8.3
[tyle...@tpb006:~/cmake-test-install-prefix]$ cat CMakeLists.txt
cmake_minimum_required(VERSION 2.8)
project(p)
set (CMAKE_INSTALL_PREFIX "foo" CACHE PATH "docstring")
message ("CMAKE_INSTALL_PREFIX = ${CMAKE_INSTALL_PREFIX}")
[tyle...@tpb006:~/cmake-test-install-prefix]$ mkdir b && cd b && cmake ..
