# QGIS Mac Bundle Macros

# BundleUtilities has functions to bundle and fixup libraries into an
# application package, but it's all-or-nothing and is missing some features:
#
# - @loader_path
# - helper functions can't get install_name, just dependencies

# the following cmakecache vars must be set, redefine them
# with config-file substitutions in install-run scripts:
#
# CPACK_PACKAGE_VERSION_MAJOR, CPACK_PACKAGE_VERSION_MINOR
# CMAKE_INSTALL_PREFIX, CMAKE_VERBOSE_MAKEFILE, CMAKE_BUILD_TYPE
# CMAKE_OSX_ARCHITECTURES, OSX_HAVE_LOADERPATH
# QGIS_APP_NAME
# QGIS_MACAPP_PREFIX
# QGIS_*_SUBDIR, QGIS_*_SUBDIR_REV
# WITH_*

# this file must only be included after target installation is complete

# message only if verbose makefiles
