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.
