Or /emul/ia32-linux, /include and /usr/include. You don't need to take 'root' literally. > anyway that's not really a problem. > 2.

You mean something like glibconfig.h. But that's why they put that under ..../lib/glib-2.0/include and not under ..../include. That's also why pkgconfig file go under ..../lib/pkgconfig for libraries and not under ..../share/pkgconfig . > I naively assumed that for doing cross compilation I would simply have > to install the 32bits version of a particular package (zlib, uuid, > expat) within a specific root (/emul/ia32-linux for instance). Sure, you can always do that. That doesn't mean you always have to if you want to save some disk space and inodes :) HS _______________________________________________ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
