## Usage:
1. For CMake projects
* Ensure LeapSDK is in a directory considered as a prefix by find_package.
(https://cmake.org/cmake/help/v3.16/command/find_package.html)
* Or : directly set LeapSDK_DIR to <install_dir>/LeapSDK/lib/cmake/LeapSDK
* Or : Pass the LeapSDK's path to find_package with the PATHS option.
* call find_package(LeapSDK 5 [PATHS ...]).
* call target_link_libraries(<your project> PUBLIC|PRIVATE LeapSDK::LeapC).
* Ensure LeapC.dll/LeapC.so is in your dynamic library search path.
* A popular option is to add a post-build step that copies it to your project's output directory.
2. For non-CMake projects
* Use a C/C++ compiler such as MSVC, Clang or GCC.
* Add LeapSDK/include to the compiler include search paths.
* Either add a linker reference to LeapC.lib or dynamically load LeapC.dll/LeapC.so.
