# levmarConfig.cmake
# ------------------
#
# levmar cmake module.
# This module sets the following variables in your project:
#
# ::
#
##   levmar_FOUND - true if levmar and all required components found on the system
##   levmar_VERSION - levmar version in format Major.Minor.Release
##   levmar_INCLUDE_DIRS - Directories where levmar header is located.
##   levmar_INCLUDE_DIR - same as DIRS
##   levmar_DEFINITIONS: Definitions necessary to use levmar, namely USING_levmar.
##   levmar_LIBRARIES - levmar library to link against.
##   levmar_LIBRARY - same as LIBRARIES
#
#
# Available components: shared static
#
# ::
#
#   shared - search for only shared library
#   static - search for only static library
#
#
## Exported targets:
##
## ::
##
## If levmar is found, this module defines the following :prop_tgt:`IMPORTED`
## target. Note that if levmar library is static, importing project must
## declare Fortran as a language in order to populate the link libs. ::
##
##   levmar::levmar - the main levmar library with header, defs, & linker lang attached.
##
##
## Suggested usage:
##
## ::
##
##   find_package(levmar)
##   find_package(levmar 1.2 EXACT CONFIG REQUIRED COMPONENTS static)
#
#
# The following variables can be set to guide the search for this package:
#
# ::
#
#   levmar_DIR - CMake variable, set to directory containing this Config file
#   CMAKE_PREFIX_PATH - CMake variable, set to root directory of this package
#   PATH - environment variable, set to bin directory of this package
#   CMAKE_DISABLE_FIND_PACKAGE_levmar - CMake variable, disables
#     find_package(levmar) when not REQUIRED, perhaps to force internal build
