I tried with the current nightly cmake binary to cross compile with
mingw tools on Darwin.
But it fails and I have no right idea what goes wrong.
First, the rc compile was not found:
+ cmake -G 'Unix Makefiles' -DCMAKE_C_COMPILER=i386-mingw32-gcc -
DCMAKE_CXX_COMPILER=i386-mingw32-g++ -DCMAKE_SYSTEM_NAME=Windows-GNU -
DCMAKE_INSTALL_PREFIX=C:/usr --check-system-vars ..
Also check system files when warning about unused and uninitialized
variables.
-- The C compiler identification is GNU 3.4.5
-- The CXX compiler identification is GNU 3.4.5
CMake Error: your RC compiler: "CMAKE_RC_COMPILER-NOTFOUND" was not
found. Please set CMAKE_RC_COMPILER to a valid compiler path or name.

Than I defined it and the host binutils are used:
+ cmake -G 'Unix Makefiles' -DCMAKE_C_COMPILER=i386-mingw32-gcc -
DCMAKE_CXX_COMPILER=i386-mingw32-g++ -DCMAKE_SYSTEM_NAME=Windows-GNU -

--check-system-vars ..
Also check system files when warning about unused and uninitialized
variables.

A a third try I defined all binutils too:
cmake -G "Unix Makefiles" \
-DCMAKE_C_COMPILER=i386-mingw32-gcc -DCMAKE_CXX_COMPILER=i386-
mingw32-g++ \
-DCMAKE_SYSTEM_NAME=Windows-GNU -DCMAKE_INSTALL_PREFIX="C:/usr" \

-DCMAKE_RANLIB=i386-mingw32-ranlib \
-DCMAKE_RC_COMPILER=i386-mingw32-windres \
..
make
...

with same result!
The ranlib and ar from build host is used.
Any idea what I should try or do would help?
