# FindLibSolv - Find libsolv headers and libraries.
#
# Sample:
#
#   SET( LibSolv_USE_STATIC_LIBS OFF )
#   FIND_PACKAGE( LibSolv REQUIRED ext )
#   IF( LibSolv_FOUND )
#      INCLUDE_DIRECTORIES( ${LibSolv_INCLUDE_DIRS} )
#      TARGET_LINK_LIBRARIES( ... ${LibSolv_LIBRARIES} )
#   ENDIF()
#
# Variables used by this module need to be set before calling find_package
# (not that they are cmale cased like the modiulemane itself):
#
#   LibSolv_USE_STATIC_LIBS	Can be set to ON to force the use of the static
#				libsolv libraries. Defaults to OFF.
#
# Supported components:
#
#   ext				Also include libsolvext
#
# Variables provided by this module:
#
#   LibSolv_FOUND		Include dir, libsolv and all extra libraries
#				specified in the COMPONENTS list were found.
#
#   LibSolv_LIBRARIES		Link to these to use all the libraries you specified.
#
#   LibSolv_INCLUDE_DIRS	Include directories.
#
# For each component you specify in find_package(), the following (UPPER-CASE)
# variables are set to pick and choose components instead of just using LibSolv_LIBRARIES:
#
#   LIBSOLV_FOUND			TRUE if libsolv was found
#   LIBSOLV_LIBRARY			libsolv libraries
#
#   LIBSOLV_${COMPONENT}_FOUND		TRUE if the library component was found
#   LIBSOLV_${COMPONENT}_LIBRARY	The libraries for the specified component
#

# Support preference of static libs by adjusting CMAKE_FIND_LIBRARY_SUFFIXES
