# - try to find MyPackage library
#
# Example-FindMyPackage-UsingImportedTargets.cmake
#
# This module does the same thing as Example-FindMyPackage.cmake
# except that rather than passing along full path names for libraries,
# it creates imported targets. The end result is roughly the same to
# the end-user. Please see that other file for the full documentation
# of the example.
#
# Note that if you're going to be installing target export files, this
# is probably what you should prefer. See cmake mailing list archives.
#
# Start of what would be a minimal module documentation block:
#
# Cache Variables: (not for direct use in CMakeLists.txt)
# MYPACKAGE_ROOT
# MYPACKAGE_LIBRARY
# MYPACKAGE_INCLUDE_DIR
# MYPACKAGE_a_LIBRARY
# MYPACKAGE_a_INCLUDE_DIR
# MYPACKAGE_b_LIBRARY
# MYPACKAGE_b_INCLUDE_DIR
# MYPACKAGE_c_LIBRARY
# MYPACKAGE_c_INCLUDE_DIR
#
# Non-cache variables you might use in your CMakeLists.txt:
# MYPACKAGE_FOUND
#
# MYPACKAGE_LIBRARIES
# MYPACKAGE_INCLUDE_DIRS
# MYPACKAGE_LINKER_FLAGS
#
# MYPACKAGE_a_LIBRARIES
# MYPACKAGE_a_INCLUDE_DIRS
# MYPACKAGE_a_LINKER_FLAGS
#
# MYPACKAGE_b_LIBRARIES
# MYPACKAGE_b_INCLUDE_DIRS
# MYPACKAGE_b_LINKER_FLAGS
#
# MYPACKAGE_c_LIBRARIES
# MYPACKAGE_c_INCLUDE_DIRS
# MYPACKAGE_c_LINKER_FLAGS
#
# Use this module this way:
# find_package(MyPackage)
# include_directories(${MYPACKAGE_INCLUDE_DIRS})
# add_executable(myapp ${SOURCES})
# target_link_libraries(myapp ${MYPACKAGE_LIBRARIES})
# set_property(TARGET myapp PROPERTY LINK_FLAGS ${MYPACKAGE_LINKER_FLAGS})
#
# Requires these CMake modules:
# FindPackageHandleStandardArgs (CMake standard module)
#
