Cross compile from linux for windows

[R1tschY]

I want to cross compile my library from linux for windows.

I use

bii configure \
  -DCMAKE_TOOLCHAIN_FILE=`pwd`/Toolchain-cross-mingw.cmake \
  -DCOMPILER_PREFIX=i686-w64-mingw32 \
  -DBII_BOOST_VERBOSE=ON

to configure with Toolchain-cross-mingw.cmake:

# the name of the target operating system
SET(CMAKE_SYSTEM_NAME Windows)

# Choose an appropriate compiler prefix

IF ("${COMPILER_PREFIX}" STREQUAL "")
    SET(COMPILER_PREFIX x86_64-w64-mingw32)
ENDIF()

# which compilers to use for C and C++
set(CMAKE_RC_COMPILER ${COMPILER_PREFIX}-windres)
set(CMAKE_C_COMPILER ${COMPILER_PREFIX}-gcc)
set(CMAKE_CXX_COMPILER ${COMPILER_PREFIX}-g++)

# here is the target environment located
SET(CMAKE_FIND_ROOT_PATH  /usr/${COMPILER_PREFIX} )

set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)

My problem is that the bootstrapping is failing:

ERROR: CMake failed

Problem seems to be in the install.cmake:

    #Bootstrap
    if(CMAKE_SYSTEM_NAME MATCHES "Windows")
        set(__BII_BOOST_BOOSTRAPER ${BII_BOOST_DIR}/bootstrap.bat ${SCOPE})
        set(__BII_BOOST_B2         ${BII_BOOST_DIR}/b2.exe        ${SCOPE})
        set(__DYNLIB_EXTENSION     .dll  
...

It uses ${BII_BOOST_DIR}/bootstrap.bat but should use ${BII_BOOST_DIR}/bootstrap.sh for cross compiling. Is there any solution?
