### To use gcc/g++ on a Macintosh, you must set the Compilers
### here, not inside the project
##if(APPLE)
##       set(CMAKE_C_COMPILER "/usr/local/bin/gcc-7")
##       set(CMAKE_CXX_COMPILER "/usr/local/bin/g++-7")
##endif()
### TODO: for now, we use CLang for Mac
###
### In order to create OpenFHE's static libraries you should enable
### the BUILD_STATIC option. For that, you run "cmake .. -DBUILD_STATIC=ON".
### After having your link completed you will find static libs
### with the suffix "_static" in ./build/libs/.
### Examples: OPENFHEpke_static.a, OPENFHEcore_static.a, etc.
### After you run "make install" in your build directory, you can build your custom application.
### If you need your application to be linked statically, then run "cmake .. -DBUILD_STATIC=ON"

project(demo CXX)
set(CMAKE_CXX_STANDARD 17)
option( BUILD_STATIC "Set to ON to include static versions of the library" OFF)
