IMPORTED Targets ^^^^^^^^^^^^^^^^ This module defines :prop_tgt:`IMPORTED` target ``LibXml2::LibXml2``, if libxml2 has been found. Result variables ^^^^^^^^^^^^^^^^ This module will set the following variables in your project: ``LIBXML2_FOUND`` true if libxml2 headers and libraries were found ``LIBXML2_INCLUDE_DIR`` the directory containing LibXml2 headers ``LIBXML2_INCLUDE_DIRS`` list of the include directories needed to use LibXml2 ``LIBXML2_LIBRARIES`` LibXml2 libraries to be linked ``LIBXML2_DEFINITIONS`` the compiler switches required for using LibXml2 ``LIBXML2_XMLLINT_EXECUTABLE`` path to the XML checking tool xmllint coming with LibXml2 ``LIBXML2_VERSION_STRING`` the version of LibXml2 found (since CMake 2.8.8) Cache variables ^^^^^^^^^^^^^^^ The following cache variables may also be set: ``LIBXML2_INCLUDE_DIR`` the directory containing LibXml2 headers ``LIBXML2_LIBRARY`` path to the LibXml2 library #]=======================================================================] # use pkg-config to get the directories and then use these values # in the find_path() and find_library() calls find_package(PkgConfig QUIET) PKG_CHECK_MODULES(PC_LIBXML QUIET libxml-2.0) set(LIBXML2_DEFINITIONS ${PC_LIBXML_CFLAGS_OTHER}) find_path(LIBXML2_INCLUDE_DIR NAMES libxml/xpath.h HINTS ${PC_LIBXML_INCLUDEDIR} ${PC_LIBXML_INCLUDE_DIRS} PATH_SUFFIXES libxml2 ) # CMake 3.9 and below used 'LIBXML2_LIBRARIES' as the name of # the cache entry storing the find_library result.
