# WARNING! EXPERIMENTAL! Use setup.py if you're not familiar with cmake.
#
# We recommend that you create a separate directory for the build,
# so that the build files aren't mixed in with the source files.
# e.g.
#  $ mkdir build-cmake
#  $ cd build-cmake
#  $ cmake ..
#  $ make
#
# MacOSX Notes:
#   On MacOSX, it may default to 64-bit, even if your Python is 32-bit.
#   The linker will give NO WARNING, and the resulting .so file will
#   fail to load in Python. To fix this, run cmake as follows,
#   assuming you're in <source dir>/build-cmake/:
#     cmake -DCMAKE_OSX_ARCHITECTURES=i386 ..
#   To debug this issue, you can compare "lipo -info `which python`"
#   with "lipo -info numexpr.so". They should have the same platform info.
#
#   Further problems on OS X appear to be related to EPD Python. CMake's
#   default detection may be detecting the wrong python to link against.
#
# Windows Notes:
#   Python 2.7 is built with Visual C++ 9 (aka 2008). This is the one
#   you should pick when running cmake-gui. Be sure to switch the build
#   configuration from Debug to Release (or RelWithDebInfo) in Visual Studio.
