# Several distros (ArchLinux, Fedora) have in the past installed libraries
# in /lib(64)?, but are now moving to install libraries in /usr/lib(64)?/.
# The /lib paths are made symlinks to the /usr/lib paths. If someone searching
# for a Qt 5 package finds it in /lib/cmake/Qt5Core, although it has been
# installed in /usr/lib/cmake/Qt5Core, relative paths to the includes and
# executables will not work.
# To work around this, we insert code into the generated config files to check
# at cmake time whether package has been found via a symlink, and correct
# that to an absolute path. This is only done for installations to
# the /usr or / prefix.

# to build debug libraries of Qt, the generated CMake file won't know about debug libraries,
