After installing Intel HE Acceleration Library for FPGAs, you can use the library in an external application in the following way.

Include Intel HE Acceleration Library for FPGAs package into your CMakeLists.txt:

``` find_package(hexl-fpga 1.1 HINTS ${HEXL_FPGA_HINT_DIR} REQUIRED) target_link_libraries(<your target>=""> PRIVATE hexl-fpga::hexl-fpga) ```

If Intel HE Acceleration Library for FPGAs is installed globally, HEXL_FPGA_HINT_DIR is not needed. Otherwise, HEXL_FPGA_HINT_DIR should be the directory containing hexl-fpgaConfig.cmake, e.g. ${CMAKE_INSTALL_PREFIX}/lib/cmake/, where ${CMAKE_INSTALL_PREFIX} is the pre-installed directory.

Build your application with preinstalled Intel HE Acceleration Library for FPGAs package

To build your application with Intel HE Acceleration Library for FPGAs, point ${CMAKE_PREFIX_PATH} to the pre-installed Intel HE Acceleration Library for FPGAs package. ``` mkdir -p build-examples cd build-examples cmake ../examples/ -DCMAKE_PREFIX_PATH=${CMAKE_INSTALL_PREFIX}/lib/cmake/ -DCMAKE_CXX_COMPILER=g++ -DCMAKE_C_COMPILER=gcc ```

Compile the examples

``` make ```

The compiled executable is located in build-examples/ directory.

Run the examples

Run the examples in emulation mode

``` export RUN_CHOICE=1 make examples ```

Run the examples on FPGA card

``` export RUN_CHOICE=2 make examples ```
