Christian Pfeiffer a62d50ec56 Modules: Replace coded PATHS with PATH_SUFFIXES
Some modules assume that `/usr` and `/usr/local` are the only
`CMAKE_PREFIX_PATH` entries and explicitly enumerate all paths instead
of using `PATH_SUFFIXES` and relying on the dynamic set of prefix paths.
This commit attempts to rectify that behavior.

# FindQt3
# -------
#
# Locate Qt include paths and libraries
#
# This module defines:
#
# ::
#
# QT_INCLUDE_DIR - where to find qt.h, etc.
# QT_LIBRARIES - the libraries to link against to use Qt.
# QT_DEFINITIONS - definitions to use when
# compiling code that uses Qt.
# QT_FOUND - If false, don't try to use Qt.
# QT_VERSION_STRING - the version of Qt found
#
#
#
# If you need the multithreaded version of Qt, set QT_MT_REQUIRED to
# TRUE
#
# Also defined, but not for general use are:
#
# ::
#
# QT_MOC_EXECUTABLE, where to find the moc tool.
# QT_UIC_EXECUTABLE, where to find the uic tool.
# QT_QT_LIBRARY, where to find the Qt library.
# QT_QTMAIN_LIBRARY, where to find the qtmain
# library. This is only required by Qt3 on Windows.
# These are around for backwards compatibility
# they will be set
# QT_WRAP_CPP, set true if QT_MOC_EXECUTABLE is found
# QT_WRAP_UI set true if QT_UIC_EXECUTABLE is found
# If Qt4 has already been found, fail.
