Re: [Cppcms-users] cmake crosscompilation problems

[Artyom <art...@ya...>]

I've notices that when I build the CppCMS for ARM I confiure all search paths 
in CMAKE_FIND_ROOT_PATH
in ToolChain.cmake file, try to use it instead of command line parameters.

Also please post the file CMakeFiles/CMakeOutput.log to see if something 
suspicios there.

Artyom

P.S.: This is why I hate CMake sometimes :-)
