-CMake build instructions:
-=========================
-Alternatively, Faiss can be built via the experimental cmake scripts.
-The installation process is similar to using Makefiles. After installing
-the necessary dependencies (OpenBLAS, OpenMP, and CUDA, if BUILD_WITH_GPU
-is enabled), the build process can be done by the following commands:
-
-```
-mkdir build
-cd build
-cmake ..
-make      # use -j to enable parallel build
-```
-
-Notes for build on Mac: The native compiler on Mac does not support OpenMP.
-So to make it work on Mac, you have to install a new compiler using either
-Macports or Homebrew. For example, after installing the compiler `g++-mp-6`
-from Macports (`port install g++-mp-6`), you need to set the two flags
-`CMAKE_CXX_COMPILER` and `CMAKE_C_COMPILER`:
-
-`cmake -DCMAKE_CXX_COMPILER=/opt/local/bin/g++-mp-6 -DCMAKE_C_COMPILER=/opt/local/bin/gcc-mp-6  ..`
-
-Similarly, you can use Homebrew to install clang++ (`brew install llvm`) and
-then set the two flags to `/usr/local/opt/llvm/bin/clang++`.
-
-CMake supports the OpenBLAS and MKL implementations. CMake limitations: the python interface is
-NOT supported at this point.
-
-Use Faiss as a 3rd-party library: Using Faiss as a 3rd-party lib via CMake is easy.
-If the parental project is also build via CMake, just add a line `add_subdirectory(faiss)`
-in CMake where faiss is the sub-folder name. To link Faiss to your application, use
-
-```
-add_executable(my_app my_app.cpp)
-target_link_libraries(my_app gpufaise faiss)
-```
