[CMake] WXDialog using UNICODE wx build again and unicode in CMake?

[Jan Woetzel]

Hi,
I am running into troubles compiling WXDialog against a WX compiled as 
UNICODE build.

Using
- CMake CVS from yesterday,
- wx UNICODE build on Linux (because the defalt Suse 10.1 supplied 
binary rpms are build with unicode)
  - wx non-Unicode "ansi" on Windows makes no problem (compiled by me),
- wx 2.6.3

With UNICODE build there are lots of errors regarding conversions 
between non-std:.string, char* and wxString, wxChar because of missing ""

The errors can be solved using
- wx underscore macro, e.g.  _("foo")
- explicit wxString contructors, e.g.  wxString(std::string.c_str(), 
wxConvUTF8)
- explcit Ascii conversion, e.g. wxString.ToAscii()
See http://www.wxwindows.org/manuals/2.6.3/wx_unicode.html

I started fixing them, then noticed Mathieu already fixed some of them 
and submitted a patch:
http://public.kitware.com/pipermail/cmake/2005-August/007058.html

(1) However, the patch was not applied to CMake CVS, right? Why not?
(2) The patch does not fix all problems in yesterdays cvs - at least 
some argv conversions (char** / wxChar**) need a fix.
(3) Has anybody solved the issue and can submit a patch that will be 
included in CVS ?

WXDialog is using the CMakeLib through its char* interfaces.
(4) Will Cmake always use ascii or are there future plans to switch 
CMake to UNICODE wchar ?
The explicit wxUTF8 conversion will only work, if Cmake itself is build 
as unicode/wchar.
Thus I have a feeling to avoid unicode in CMakeLib interfaces.

I like WXDialog more than than MFCDialog/Cursesdialog because
- running the same gui on Windows and Linux is great,
- WXDialog does not jump to beginning of list after deleting a single 
cache entry.

To conclude:
Great work , Jorgen!
We just need 1% more coding to make it useable with Unicode builds which 
seem to be default at least on Linux, now.

Best,
Jan
