In general determining install locations are the responsibility of the project 
which is being built. I mean, if I chose to install something to $HOME/inst 
it shouldn't matter where PolkitQt is installed.

What we do for the other install dirs like BIN_INSTALL_DIR etc. in kdelibs is 
the following:
if the variable (e.g. KDE4_AUTH_POLICY_FILES_INSTALL_DIR) has not been 
explicitely set, and if the current CMAKE_INSTALL_PREFIX is the same as the 
kdelibs install prefix, then we reuse the variable (e.g. 
KDE4_AUTH_POLICY_FILES_INSTALL_DIR) from kdelibs.

Look for the macro _SET_FANCY() in 
kdelibs/cmake/modules/FindKDE4Internal.cmake.

Does this do what you want ?
