You should use a target specific version of 'pkgconfig' (e.g. arm-linux-gnu-pkgconfig) which is configured with a proper searchpath. Dunno about the cmake cross stuff (-> effect of find_program()), but autoconf probes for programs (AC_CHECK_TOOLS) by prefixing the target tuple when crosscompiling (e.g. check for 'arm-xscale-linux-gnu-FOO' instead of 'FOO'). Another way might be to provide a $PATH which prefers cross-tools to native ones (e.g. /usr/arm-xscale-linux-gnu/bin/gcc instead of /usr/bin/gcc). In both ways, the cross-pkgconfig can be specified on the cmake commandline: | cmake -DPKG_CONFIG_EXECUTABLE=arm-xscale-linux-gnu-pkgconfig Enrico _______________________________________________ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
