FindLibXslt
-----------
Find the XSL Transformations, Extensible Stylesheet Language
Transformations (XSLT) library (LibXslt)
IMPORTED Targets
^^^^^^^^^^^^^^^^
.. versionadded:: 3.18
The following :prop_tgt:`IMPORTED` targets may be defined:
``LibXslt::LibXslt``
If the libxslt library has been found
``LibXslt::LibExslt``
If the libexslt library has been found
``LibXslt::xsltproc``
If the xsltproc command-line executable has been found
Result variables
^^^^^^^^^^^^^^^^
This module will set the following variables in your project:
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_INCLUDE_DIR``
.. versionadded:: 3.18
The include directory for exslt.
``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.

# in the find_path() and find_library() calls
