[CMake] CMake with wxWidgets on Linux

[Brian Eastwood]

Hi All,

I've been using CMake for a few years on Windows and recently switched 
over to Linux.  I have been having some problems getting a basic hello 
world program running using wxWidgets, and figured someone here probably 
know what I am doing wrong.  Part of my confusion is the large number of 
cmake files that could be used to configure wxWidgets.  My CMakeLists 
file is copied below.  The program hworld.cxx is basically Robert 
Roebling's hello world tutorial from http://www.wxwidgets.org/hello.htm

I have no problems running cmake or compiling the project, but get a 
segmentation fault when I try running the program...there is no other 
output.  (I'm assuming the application can't find a shared library, but 
I don't know which one that would be.)

I am running Fedora Core 5 and installed wxGTK, wxGTK-devel and 
compat-wxGTK2-devel (among others) from the fedora extras rpm 
repository.  Are there other packages I should have installed?

Thanks in advance for any suggestions.
Cheers,
Brian
