The package libxslt is compatible with built-in CMake targets:

    # xslt library
    find_package(LibXslt REQUIRED)
    target_link_libraries(main PRIVATE LibXslt::LibXslt)

    # exslt library
    find_package(LibXslt REQUIRED)
    target_link_libraries(main PRIVATE LibXslt::LibExslt)

In order to use modules, you must set environment variable LIBXSLT_PLUGINS_PATH
at runtime.
