# This allows controlling documented build time switches
# when Expat is pulled in using the add_subdirectory function, e.g.
#
# set(EXPAT_BUILD_DOCS OFF)
# set(EXPAT_BUILD_TOOLS OFF)
# add_subdirectory(${expat_SOURCE_DIR}/expat ${expat_BINARY_DIR})
#
# would disable compilation of the xmlwf CLI and its man page.
# Without activating behaviour NEW for policy CMP0077 here,
# a user with -Wdev enabled would see warning
#
# Policy CMP0077 is not set: option() honors normal variables. Run "cmake
# --help-policy CMP0077" for policy details. Use the cmake_policy command to
# set the policy and suppress this warning.
#
# For compatibility with older versions of CMake, option is clearing the
# normal variable 'EXPAT_BUILD_DOCS'.
#
# and effectively not be able to adjust option EXPAT_BUILD_DOCS.

# For more details please see:
