where to install FooConfig.cmake files - removing the KDE4_USE_COMMON_CMAKE_PACKAGE_CONFIG_DIR option

[Alexander Neundorf]

Hi,

currently FindKDE4Internal.cmake provides the 
KDE4_USE_COMMON_CMAKE_PACKAGE_CONFIG_DIR option if cmake >= 2.6.3.
This is now always the case (since we require 2.6.4 now).

When enabled (which is the default), other KDE modules can use this option to 
decide whether their FooConfig.cmake files should be installed to 
lib/foo/cmake/ (when disabled) or lib/cmake/foo/ (when enabled).

Any objections to removing this option and always install to lib/cmake/foo/ ?
