Milan,

I guess you have a CMake toolchain file for the cross build already in hand?



I would troubleshoot the lines

find_package(wxWidgets COMPONENTS gl html adv core net base QUIET)
check_find_package_result(wxWidgets_FOUND "wxWidgets")

in the topmost CMakeList.txt file.

The first line is a type of file include, which pulls in a file by the 
name of:

/usr/share/cmake-2.6/Modules/FindwxWidgets.cmake

on my system. On your system, this may be a different file. 
What is important is that this file is not part of Kicad that I can 
see. The *.cmake files can come from either the <kicad>/CMakeModules 
directory or from the cmake standard directory, which on my system is

/usr/share/cmake-2.6/Modules/



Here is what I recommend:


1) copy your FindwxWidgets.cmake file from its standard place to 
<kicad>/CMakeModules where you can edit it without being root.

2) Pull it up in a text editor, and try and understand it with the CMake 
documentation in hand.


3) add

message( variable=${variable} )

like statements liberally to "debug" the file at various points in the 
execution sequence.


4) Always use an out of tree build, and remove your CMakeCache.txt file 
between attempts.


5) If you find the problem, we can then commit your changes and include 
them as part of <kicad>/CMakeModules/FindwxWidgets.cmake. However any 
changes must also work with standard windows and standard linux.


6) If all else fails, you can run "ccmake . " in your out of tree build 
directory and try and manually satisfy the things that 
FindwxWidgets.cmake is looking for. Its goal is to set some variables 
into the CMakeCache.txt file, but you can do that manually with "ccmake 
. " in your build directory.
