Re: [Mingw-cross-env-list] Question and Help

[Omar Andrés Zapata Mesa]

 ok thank you very much,
 I will work on this and I'll make a howto and a cmake .find file,
maybe you want put this contribution in your website and this will be my contribution to short-term.

 another thing is that we should standardize the path where to get the software installed by default, to write general cmake files.

Generic cross compilation instructions for CMake can be found here:
http://www.cmake.org/Wiki/CMake_Cross_Compiling

You have to set various options to tell CMake what kind of system you
want to compile for and where to find the proper include and l so muchibrary
files.

Mingw-cross-env uses this for the OpenSceneGraph package, see
src/openscenegraph.mk.

If you have Mingw-cross-env installed in e.g. /MCE, then you would use
something like this:

cmake . \
 -DCMAKE_SYSTEM_NAME=Windows \
 -DCMAKE_FIND_ROOT_PATH=/MCE/usr/i686-pc-mingw32 \
 -DCMAKE_FIND_ROOT_PATH_MODE_PROGRAM=NEVER \
 -DCMAKE_FIND_ROOT_PATH_MODE_LIBRARY=ONLY \
 -DCMAKE_FIND_ROOT_PATH_MODE_INCLUDE=ONLY \
 -DCMAKE_C_COMPILER=/MCE/usr/bin/i686-pc-mingw32-gcc' \
 -DCMAKE_INCLUDE_PATH=/MCE/usr/i686-pc-mingw32/include \
 -DCMAKE_LIB_PATH=/MCE/usr/i686-pc-mingw32/lib \
 -DPKG_CONFIG_EXECUTABLE=/MCE/usr/bin/i686-pc-mingw32-pkg-config

However, the project might still use some CMake macros or scripts that
do not support cross compilation and need to be fixed manually.
