[CMake] FindBoost problem when cross-compiling

[ross hennessy]

I'm having a problem with FindBoost.cmake with cmake 2.6.3 under win32 when
cross-compiling only ( I have boost version 1.38.0). I have the environment
variable BOOST_ROOT set to the directory containing the install of boost. If
I build my project using "default native compilers" for VS 2008 the
FindBoost works fine. When I select "specify toolchain for crosscompiling"
to build for QNX Momentics, the FindBoost stops working. Can somebody please
help me out as I've spent some time to look into this and it doesn't seem to
be an incorrect usage of FindBoost. Here is the output from cmake when I hit
configure -

The Boost_INCLUDE_DIR should be set to C:/dev/libraries/boost/boost_1_38_0
which is what happens when I build natively instead of crosscompiling. I'm
basically down to the one line (454) in FindBoost.cmake where it calls
FIND_PATH for boost/config.hpp and all inputs look correct so I can't do any
further debugging to work out what is failing. The only thing I can think of
is that the QNX.cmake platform file is included from the toolchain file,
which in turn includes the UnixPaths.cmake which means UNIX is set, but
WIN32 isn't (I'm not sure how this would affect FIND_PATH though?).

Thanks, Ross
