Summary0014004: FindSDL fails to find headers for cross-compilation
DescriptionFindSDL fails to find the SDL include headers for cross compilation. I have a MXE (http://mxe.cc [^]) cross-compilation environment set up at $HOME/win32/mxe/usr/i686-pc-mingw32 which includes a cross-compiled SDL library for mingw32 (the host system is a 64-bit Arch Linux). Here’s a list of all SDL-related files installed under that root directory: http://pastie.org/6461937 [^]

Exact error from CMake:

====================================================
CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:97 (message):
  Could NOT find SDL (missing: SDL_INCLUDE_DIR)
Call Stack (most recent call first):
  /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:291 (_FPHSA_FAILURE_MESSAGE)
  /usr/share/cmake-2.8/Modules/FindSDL.cmake:178 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  CMakeLists.txt:40 (find_package)

====================================================

In order to cross-compile, I then set CMAKE_FIND_ROOT_PATH in my toolchain file:


====================================================
set(CMAKE_SYSTEM_NAME Windows)
set(CMAKE_FIND_ROOT_PATH "$ENV{HOME}/win32/mxe/usr/i686-pc-mingw32")
====================================================

And of course, I also set the other necessary variables:

====================================================
set(CMAKE_C_COMPILER i686-pc-mingw32-gcc)
set(CMAKE_CXX_COMPILER i686-pc-mingw32-g++)
set(CMAKE_RC_COMPILER i686-pc-mingw32-windres)
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
====================================================

This is the cross-compiler:

====================================================
% i686-pc-mingw32-gcc --version
i686-pc-mingw32-gcc (GCC) 4.7.2

====================================================
Steps To Reproduce1. Create a SDL installation for mingw32 somewhere
2. Create CMakeLists.txt that calls find_package(SDL REQUIRED)
3. Create a toolchain file for cross-compilation from Linux to mingw32, variables see above, ensure CMAKE_FIND_ROOT_PATH includes the root of your SDL installation
4. Invoke CMake with -DCMAKE_TOOLCHAIN_FILE=/path/to/toolchain/file
5. CMake fails to find the SDL headers.

Please check if the bug also affects 2.8.11-rc1 [1], because the new version contains a fix concerning SDL search directories (see issue 0013819 [2]).
