The install prefix should never have been set with a trailing slash. 
Your install rules should use leading slashes if you are using 
INSTALL_TARGETS, INSTALL_FILES, or INSTALL_PROGRAMS.  If you switch to 
using the INSTALL command in 2.4.2 (not compatible with 2.2 though), 
then you do not need a leading slash.
