Commit dac78148 (...makes the mingw cross compiler work out of the box..., 2007-08-02) added to CMAKE_SYSTEM_PROGRAM_PATH and CMAKE_SYSTEM_LIBRARY_PATH paths like "/bin" and "/lib" with no Windows drive letter so that cross-compiling to Windows from Linux would search these paths under CMAKE_FIND_ROOT_PATH. Later commit 2a782880 (...use CMAKE_SYSTEM_PREFIX_PATH when possible, 2008-01-16) generalized this approach by instead adding "/" to CMAKE_SYSTEM_PREFIX_PATH. Both commits assumed that the paths would never match anything on Windows hosts without a drive letter. However, Windows evaluates these paths relative to the current working drive letter so find_* commands may report paths like "/lib/..." when paths like "c:/lib/..." exist on what happens to be current drive. Such drive-less paths are not reliable when the working drive changes, so we should not use them. Fix WindowsPaths.cmake to add '/' to CMAKE_SYSTEM_PREFIX_PATH only when cross-compiling to Windows from a non-Windows host. This will avoid searching and finding local paths without a drive letter on Windows.
This is CMake, the cross-platform, open-source make system. CMake is distributed under the BSD License, see Copyright.txt. For documentation see the Docs/ directory once you have built CMake or visit http://www.cmake.org. Building CMake ============== Supported Platforms ------------------- MS Windows, Mac OS X, Linux, FreeBSD, Solaris, HP-UX, IRIX, BeOS, QNX Other UNIX-like operating systems may work too out of the box, if not it shouldn't be a major problem to port CMake to this platform. Contact the CMake mailing list in this case: http://www.cmake.org/mailman/listinfo/cmake If you don't have any previous version of CMake already installed -------------------------------------------------------------- * UNIX/Mac OSX/MinGW/MSYS/Cygwin: You need to have a compiler and a make installed. Run the bootstrap script you find the in the source directory of CMake. You can use the --help option to see the supported options. You may want to use the --prefix=<install_prefix> option to specify a custom installation directory for CMake. You can run the bootstrap script from within the CMake source directory or any other build directory of your choice. Once this has finished successfully, run make and make install. So basically it's the same as you may be used to from autotools-based projects: $ ./bootstrap; make; make install * Other Windows: You need to download and install a binary release of CMake in order to build CMake. You can get these releases from http://www.cmake.org/HTML/Download.html . Then proceed with the instructions below. You already have a version of CMake installed --------------------------------------------- You can build CMake as any other project with a CMake-based build system: run the installed CMake on the sources of this CMake with your preferred options and generators. Then build it and install it. For instructions how to do this, see http://www.cmake.org/HTML/RunningCMake.html
