## Usage
### Way 1: import targets
Build xxHash targets:
cd </path/to/xxHash/>
mkdir build
cd build
cmake ../cmake_unofficial [options]
cmake --build .
cmake --build . --target install #optional
Where possible options are:
- `-DXXHASH_BUILD_ENABLE_INLINE_API=<ON|OFF>`: adds xxhash.c for the `-DXXH_INLINE_ALL` api. ON by default.
- `-DXXHASH_BUILD_XXHSUM=<ON|OFF>`: build the command line binary. ON by default
- `-DBUILD_SHARED_LIBS=<ON|OFF>`: build dynamic library. ON by default.
- `-DCMAKE_INSTALL_PREFIX=<path>`: use custom install prefix path.
Add lines into downstream CMakeLists.txt:
find_package(xxHash 0.7 CONFIG REQUIRED)
...
target_link_libraries(MyTarget PRIVATE xxHash::xxhash)
### Way 2: Add subdirectory
Add lines into downstream CMakeLists.txt:
option(BUILD_SHARED_LIBS "Build shared libs" OFF) #optional
...
set(XXHASH_BUILD_ENABLE_INLINE_API OFF) #optional
set(XXHASH_BUILD_XXHSUM OFF) #optional
add_subdirectory(</path/to/xxHash/cmake_unofficial/> </path/to/xxHash/build/> EXCLUDE_FROM_ALL)
...
target_link_libraries(MyTarget PRIVATE xxHash::xxhash)
