#
# This module can find INDI Library
#
# Requirements:
# - CMake >= 2.8.3 (for new version of find_package_handle_standard_args)
#
# The following variables will be defined for your use:
# - INDI_FOUND : were all of your specified components found (include dependencies)?
# - INDI_WEBSOCKET : was INDI compiled with websocket support?
# - INDI_INCLUDE_DIR : INDI include directory
# - INDI_DATA_DIR : INDI include directory
# - INDI_LIBRARIES : INDI libraries
# - INDI_DRIVER_LIBRARIES : Same as above maintained for backward compatibility
# - INDI_VERSION : complete version of INDI (x.y.z)
# - INDI_MAJOR_VERSION : major version of INDI
# - INDI_MINOR_VERSION : minor version of INDI
# - INDI_RELEASE_VERSION : release version of INDI
# - INDI_<COMPONENT>_FOUND : were <COMPONENT> found? (FALSE for non specified component if it is not a dependency)
#
# For windows or non standard installation, define INDI_ROOT variable to point to the root installation of INDI. Two ways:
# - run cmake with -DINDI_ROOT=<PATH>
# - define an environment variable with the same name before running cmake
# With cmake-gui, before pressing "Configure":
# 1) Press "Add Entry" button
# 2) Add a new entry defined as:
# - Name: INDI_ROOT
# - Type: choose PATH in the selection list
# - Press "..." button and select the root installation of INDI
#
# Example Usage:
#
# 1. Copy this file in the root of your project source directory
# 2. Then, tell CMake to search this non-standard module in your project directory by adding to your CMakeLists.txt:
# set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR})
# 3. Finally call find_package() once, here are some examples to pick from
#
# Require INDI 1.4 or later
# find_package(INDI 1.4 REQUIRED)
#
# if(INDI_FOUND)
# include_directories(${INDI_INCLUDE_DIR})
# add_executable(myapp myapp.cpp)
# target_link_libraries(myapp ${INDI_LIBRARIES})
# endif(INDI_FOUND)
#
#
# Using Components:
#
# You can search for specific components. Currently, the following components are available
# * driver: to build INDI hardware drivers.
# * align: to build drivers that use INDI Alignment Subsystem.
# * client: to build pure C++ INDI clients.
# * clientqt5: to build Qt5-based INDI clients.
# * lx200: To build LX200-based 3rd party drivers (you must link with driver above as well).
#
# By default, if you do not specify any components, driver and align components are searched.
#
# Example:
#
# To use INDI Qt5 Client library only in your application:
#
# find_package(INDI COMPONENTS clientqt5 REQUIRED)
#
# if(INDI_FOUND)
# include_directories(${INDI_INCLUDE_DIR})
# add_executable(myapp myapp.cpp)
# target_link_libraries(myapp ${INDI_LIBRARIES})
# endif(INDI_FOUND)
#
# To use INDI driver + lx200 component in your application:
#
# find_package(INDI COMPONENTS driver lx200 REQUIRED)
#
# if(INDI_FOUND)
# include_directories(${INDI_INCLUDE_DIR})
# add_executable(myapp myapp.cpp)
# target_link_libraries(myapp ${INDI_LIBRARIES})
# endif(INDI_FOUND)
#
# Notice we still use ${INDI_LIBRARIES} which now should contain both driver & lx200 libraries.
