Hi,
I've been using 2.4.7 until this morning when I saw the 2.4.8
announcement
and jumped right away to install it (silly me).
I have some script that finds Qt4 but stopped working on 2.4.8.
Tracing the problem in FindQt4.cmake I found this...
There is one (at least one) SET command like this:
SET( QT_INCLUDE_DIR ${qt4_include_dir} CACHE PATH "")
which fails to actually set the value of QT_INCLUDE_DIR
It works fine if DOCSTRING is prepended in front of "":
SET( QT_INCLUDE_DIR ${qt4_include_dir} CACHE PATH DOCSTRING "")
I just realized that the trailing "" in the original is the DOCSTRING
already.
My version works because the presence of my own trailing "" causes the
set command not to parse CACHE correctly, so it just adds "CACHE",
"PATH" and "DOCSTRING" to the variable (whith the value of
qt4_include_dir as the first element on the list)
Since that showned that this behaviour is related to caching the just
assigned value in the cache, I tried simply adding FORCE at the end, and
it worked.
Removing the cache still doesn't help unless I add FORCE, so is not an
issue caused by a previous value.
Running the script a second time (so the cache contains
"QT_INCLUDE_DIR-NOT_FOUND") still doesn't change anything.
Any ideas?
Can you add a :
message(" ${qt4_include_dir} ") right before the set statement?
Also, what is the value of QT_QTCORE_INCLUDE_DIR? You also did not say
exactly what went wrong? Did you get an error? What is the value of
QT_INCLUDE_DIR in your cache?
