Hi Werner:

I have made a small test project (as of revision 8467) for the
cmake_link_flags macro which can be obtained as follows:

svn checkout
https://plplot.svn.sourceforge.net/svnroot/plplot/branches/test_cmake/test_cmake_link_flags
test_cmake_link_flags

On Linux, here are the current results of running cmake on
test_cmake_link_flags.

[...]
flags_in = -framework QuickTime -framework IOKit -framework Carbon
-framework Cocoa -framework System  -lIDL-2
flags_out =
-framework;QuickTime;-framework;IOKit;-framework;Carbon;-framework;Cocoa;-framework;System;/usr/lib/libIDL-2.so
flags_in = -pthread   -lwx_gtk2u_xrc-2.6 -lwx_gtk2u_qa-2.6
-lwx_gtk2u_html-2.6 -lwx_gtk2u_adv-2.6 -lwx_gtk2u_core-2.6
-lwx_baseu_xml-2.6 -lwx_baseu_net-2.6 -lwx_baseu-2.6
flags_out =
-pthread;/usr/lib/libwx_gtk2u_xrc-2.6.so;/usr/lib/libwx_gtk2u_qa-2.6.so;/usr/lib/libwx_gtk2u_html-2.6.so;/usr/lib/libwx_gtk2u_adv-2.6.so;/usr/lib/libwx_gtk2u_core-2.6.so;/usr/lib/libwx_baseu_xml-2.6.so;/usr/lib/libwx_baseu_net-2.6.so;/usr/lib/libwx_baseu-2.6.so

For the first string I used your string with substitution of
a valid library on Linux which had a name in similar style
to the Mac's -lwx_macud-2.8 just in case the hyphen in the name was causing
problems, but that turned out to be no problem.  For the second string I
used the actual results of "wx-config --libs" on my Linux platform.

For both strings, everything seems to be working fine on Linux so the
problem you have found appears to be platform-dependent.  Thus,it is going
to take some debugging effort from you on your Mac OS X platform to figure
out the cause of the problem. I will help as much as I can from the
sidelines.

Once you can get to your Mac platform next week, I will be most interested
in whether the results returned from "wx-config --libs" differ any from the
wxWidgets_LIBRARIES variable returned from find_package(wxWidgets QUIET).
(The (1) and (2) results requested in my previous post).
When doing the comparison of the two strings I would be especially careful
of any special characters that might be embedded in either string.

I will also be interested in the results for the above simple test using
your "wx-config --libs" results string as input (and also the string result
from wxWidgets_LIBRARIES if that varies in any way from the other).

N.B. you must edit the CMakeLists.txt file in the simple test to change the
strings you are testing.
