| # FindLibXml2 |
| # ----------- |
| # |
| # Find the XML processing library (libxml2). |
| # |
| # 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 |
