CMake/Modules/FindLibXslt.cmake

# - 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
