When I run "cmake ." in a terminal window, I get the following output:
Don't do in-source builds, for they lead to suffering. Check the FAQ for
details.
-- /usr/lib/wx/include/gtk2-unicode-release-2.8/usr/include/wx-2.8

-- Generating done
The first line gives the value of "wxWidgets_INCLUDE_DIRS" which is
obviously wrong. It seems 2 paths have been concatenated without white
space. I think it should be something like
"/usr/lib/wx/include/gtk2-unicode-release-2.8 /usr/include/wx-2.8".
Try message(STATUS "${wxWidgets_INCLUDE_DIRS}"). My guess is that
variable is a list and the way you are using it in message() is
flattening that list.
I've just found the error I made. I defined another CMakeLists.txt file
in a sub-directory containing the source code. Unfortunately, I declared
it in the root CMakeLists.txt file (using the command add_subdirectory)
after the wxwidgets macros, because I thought that it would be processed
after the main file. But this is not the case: it seems the
add_subdirectory command immediately processes the sub-directory's
CMakeLists.txt file, so that the wxwidgets include paths were not
defined in the sub-directory's generated Makefile.
Thank you all very much for your help,
Florent
