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.
