#### QT

# The way qt and its tools (qmake especially) are installed is very

# different between systems (and maybe qt versions)

#

# In general we need QTDIR to be set, because it is used inside the

# qmake-generated makefiles. But there are exceptions: ie on debian3.1 (at

# least on the sourceforge compile farm), QTDIR is not needed because qmake

# generates hard paths (and is installed in /usr/bin). We don't want to

# force the user to set QTDIR if it is not needed.

#

# The logic is then to first look for qmake, possibly using QTDIR if it is

# set.

# 

# If QTDIR is not set, we then generate a bogus qt project and check if

# QTDIR is needed in the Makefile, in which case we complain.

#

# QMAKESPEC: on most Linux system, there is a 'default' link inside the

# mkspecs directory, so that QMAKESPEC is not needed.

# If QMAKESPEC is not set and needed, the qmake test at the previous test

# will have failed, and we tell the user to check his environment.
