# FindLibXslt
# -----------
#
# Try to find the LibXslt library
#
# Once done this will define
#
# ::
#
# LIBXSLT_FOUND - system has LibXslt
# LIBXSLT_INCLUDE_DIR - the LibXslt include directory
# LIBXSLT_LIBRARIES - Link these to LibXslt
# LIBXSLT_DEFINITIONS - Compiler switches required for using LibXslt
# LIBXSLT_VERSION_STRING - version of LibXslt found (since CMake 2.8.8)
#
# Additionally, the following two variables are set (but not required
# for using xslt):
#
# ``LIBXSLT_EXSLT_LIBRARIES``
# Link to these if you need to link against the exslt library.
# ``LIBXSLT_XSLTPROC_EXECUTABLE``
# Contains the full path to the xsltproc executable if found.
# use pkg-config to get the directories and then use these values
# in the find_path() and find_library() calls
