Zitat von Giampiero Salvi <gia...@kth.se>:
I have a project that builds fine both on Linux and on mingw32 using
cmake version 2.6-patch 2.
Now, I am trying to cross compile my project on a Linux (Ubuntu 9.04)
machine for the target Windows platform using the mingw32 cross
compiler. I have a toolchain more or less copied from
http://www.itk.org/Wiki/CmakeMingw that looks like this:
[...]
I get the error:
CMake Error at /usr/share/cmake-2.6/Modules/FindSWIG.cmake:55 (MESSAGE):
SWIG was not found. Please specify Swig executable location
This is caused by CMAKE_FIND_ROOT_PATH_MODE_INCLUDE not only affecting
include files but all files found with find_path() or find_file().
FindSWIG.cmake needs a NO_CMAKE_FIND_ROOT_PATH at the end of the
find_path() call since it will most likely always be the one on the
host (any other will give you wrong paths).
The find_program() on top of it definitely needs a
NO_CMAKE_FIND_ROOT_PATH as it is used for execution just below of that.
Not all cmake modules are ready to be used for cross-compiling and
some probably will never (e.g. FindQt4.cmake).
