[Cmake] Using Cross GCC with VC++ ide

[Nitin Gupta]

Thanks a lot for helping this out! It works.

Now I'm working towards creating an instance of
cmDependInformation by invoking FindDependencies(char *)
for each file from the plugin. Then pass the set of file
(; separated) to SourceFileSetProperty. For this I think
I need to add the a function pointer to cmCAPI cmStaticCAPI
in cmcpluginapi.cxx; say char * cmFindDependencies(char *).
Or is there already a way of doing this?

Then I plan to populate the source file property of each file
so that cmLocalVisualStudio6Generator::WriteDSPFile invokes
WriteCustomRule() with appropriate args. I think this should
take care of all the issues of cross building and browsing
in VC++.

Since all the build configuration can be kept in a <target>.cmake file
in Modules dir as CMake already does of other platforms. It will be good
to hide all this extra processing in plugin/cmake itself and the
developer need not do extra effort of writing an extra custom
command for each source file in its CMakeLists.txt file. Only thing one
would need to do is include <target>.cmake file at the top of its
CMakeList.txt. So for that the plugin should be able to extract
Include files, C flags, link flags, defines, output dir etc.

Please let me know your views about this solution.

Thanks and Regards,
Nitin
