#
# CMake script for finding TinyXML.
#
# Input variables:
#
# - TinyXML_ROOT_DIR (optional): When specified, header files and libraries will be searched for in
# ${TinyXML_ROOT_DIR}/include
# ${TinyXML_ROOT_DIR}/libs
# respectively, and the default CMake search order will be ignored. When unspecified, the default
# CMake search order is used.
# This variable can be specified either as a CMake or environment variable. If both are set,
# preference is given to the CMake variable.
# Use this variable for finding packages installed in a nonstandard location, or for enforcing
# that one of multiple package installations is picked up.
#
#
# Cache variables (not intended to be used in CMakeLists.txt files)
#
# - TinyXML_INCLUDE_DIR: Absolute path to package headers.
# - TinyXML_LIBRARY: Absolute path to library.
#
#
# Output variables:
#
# - TinyXML_FOUND: Boolean that indicates if the package was found
# - TinyXML_INCLUDE_DIRS: Paths to the necessary header files
# - TinyXML_LIBRARIES: Package libraries
#
#
# Example usage:
#
# find_package(TinyXML)
# if(NOT TinyXML_FOUND)
# # Error handling
# endif()
# ...
# include_directories(${TinyXML_INCLUDE_DIRS} ...)
# ...
# target_link_libraries(my_target ${TinyXML_LIBRARIES})
