||||
# Clang_VERSION - Clang version as reported by Clang executable
|
||||
#
|
||||
# The following :prop_tgt:`IMPORTED` targets are also defined::
|
||||
#
|
||||
# Clang::Clang - Target for all required Clang libraries and headers
|
||||
#
|
||||
# This module reads hints about which libraries to look for and where to find
|
||||
# them from the following variables::
|
||||
#
|
||||
# CLANG_CXX - Search for and add Clang C++ libraries
|
||||
# CLANG_ROOT - If set, only look for Clang components in CLANG_ROOT
|
||||
#
|

# Example to link against Clang target::
|

#
|

# target_link_libraries(<target> PRIVATE Clang::Clang)
