Get trunk/KDE/kdelibs/ from some time ago, e.g. june. Then have a look at kdelibs/kdecore/CMakeLists.txt, I think it is (was) compiled into libkdecore. There are a bunch of configure checks in kdelibs/ConfigureChecks.cmake. If you have more questions, feel free to aks :-) Bye Alex -- Der GMX SmartSurfer hilft bis zu 70% Ihrer Onlinekosten zu sparen!

I am having considerable difficulty trying to understand the m4 language in acinclude.m4 that determines LIBADD_DL. So if some project has already done all the necessary cross-platform library configuration of libltdl in the CMake language I would be grateful if somebody in the know for that project (e.g., Alex for KDE) would share that information.

I think maybe I didn't explain my question well enough.
It seems that your suggestion would allow me to compile a c/cpp file
against the matlab mex library, but what I want to do is compile a file
for use in Matlab using the mex compiler. I can do this by hand by
executing the following in a shell:
$ mex foo.cpp
This would produce a foo.mexglx binary which matlab would be able to use.
This is great if your foo.cpp is self-contained, however my foo.cpp
depends on libraries and include files which I generate in my CMake
build. Manually what I would do to handle this is:
$ mex -I/my/include/path -L/my/library/path -lmylib ... foo.cpp
I would like to make a CMake target which does the command above, taking
into account any library or include dependencies I specify in my
CMakeLists.txt. Is this possible?
Thanks,
-wojciech

Try dropping the Boolean logic and FORCE. i.e., use just

CACHE PATH "Install path prefix")
That style works for us to provide a default option that can be changed by
the user. I assume that style will also work to override a variable that has
already been cached, but I don't know for sure.

All the CMake tests are run with build-and-test:
http://www.cmake.org/cgi-bin/viewcvs.cgi/Source/CMakeLists.txt?rev=1.301&root=CMake&view=markup
VTK uses build-and-test to build an examples sub-project in a custom target:
http://www.vtk.org/cgi-bin/viewcvs.cgi/Examples/CMakeLists.txt?rev=1.31&view=markup
Look near the lines
ADD_CUSTOM_COMMAND(
OUTPUT ${VTK_BINARY_DIR}/VTKExamples
You could also consider making this one big build tree. You can use
EXECUTE_PROCESS to run programs to get things from the net and extract
the source trees. Then just use ADD_SUBDIRECTORY to include the source
trees in your build. A bit more complication may be needed to not get
the source over and over. Using IF(FILE_IS_NEWER) may help.
