Imported Targets ^^^^^^^^^^^^^^^^ This module provides the following :ref:`Imported Targets`: ``XalanC::XalanC`` Target encapsulating the Xalan-C++ library usage requirements, available only if Xalan-C++ is found. Result Variables ^^^^^^^^^^^^^^^^ This module defines the following variables: ``XalanC_FOUND`` Boolean indicating whether (the requested version of) Xalan-C++ was found. ``XalanC_VERSION`` The version of the found Xalan-C++ library. ``XalanC_INCLUDE_DIRS`` Include directories needed for using Xalan-C++ library. These contain the Xalan-C++ and Xerces-C++ headers. ``XalanC_LIBRARIES`` Libraries needed to link against Xalan-C++. These contain the Xalan-C++ and Xerces-C++ libraries. ``XalanC_LIBRARY`` The path to the Xalan-C++ library (``xalan-c``), either release or debug variant. Cache Variables ^^^^^^^^^^^^^^^ The following cache variables may also be set: ``XalanC_INCLUDE_DIR`` The directory containing the Xalan-C++ headers. ``XalanC_LIBRARY_RELEASE`` The path to a release (optimized) variant of the Xalan-C++ library. ``XalanC_LIBRARY_DEBUG`` The path to a debug variant of the Xalan-C++ library. Examples ^^^^^^^^ Finding Xalan-C++ library and linking it to a project target: .. code-block:: cmake find_package(XalanC) target_link_libraries(project_target PRIVATE XalanC::XalanC) #]=======================================================================] cmake_policy(PUSH) cmake_policy(SET CMP0159 NEW) # file(STRINGS) with REGEX updates CMAKE_MATCH_ # Written by Roger Leigh function(_XalanC_GET_VERSION version_hdr) file(STRINGS ${version_hdr} _contents REGEX "^[ \t]*#define XALAN_VERSION_.*") if(_contents) string(REGEX REPLACE "[^*]*#define XALAN_VERSION_MAJOR[ \t(]+([0-9]+).*" "\\1" XalanC_MAJOR "${_contents}") string(REGEX REPLACE "[^*]*#define XALAN_VERSION_MINOR[ \t(]+([0-9]+).*" "\\1" XalanC_MINOR "${_contents}") string(REGEX REPLACE "[^*]*#define XALAN_VERSION_REVISION[ \t(]+([0-9]+).*" "\\1" XalanC_PATCH "${_contents}") if(NOT XalanC_MAJOR MATCHES "^[0-9]+$") message(FATAL_ERROR "Version parsing failed for XALAN_VERSION_MAJOR!") endif() if(NOT XalanC_MINOR MATCHES "^[0-9]+$") message(FATAL_ERROR "Version parsing failed for XALAN_VERSION_MINOR!") endif() if(NOT XalanC_PATCH MATCHES "^[0-9]+$") message(FATAL_ERROR "Version parsing failed for XALAN_VERSION_REVISION!") endif() set(XalanC_VERSION "${XalanC_MAJOR}.${XalanC_MINOR}.${XalanC_PATCH}" PARENT_SCOPE) set(XalanC_VERSION_MAJOR "${XalanC_MAJOR}" PARENT_SCOPE) set(XalanC_VERSION_MINOR "${XalanC_MINOR}" PARENT_SCOPE) set(XalanC_VERSION_PATCH "${XalanC_PATCH}" PARENT_SCOPE) else() message(FATAL_ERROR "Include file ${version_hdr} does not exist or does not contain expected version information") endif() endfunction() # Find include directory find_path(XalanC_INCLUDE_DIR NAMES "xalanc/XalanTransformer/XalanTransformer.hpp" DOC "Xalan-C++ include directory") mark_as_advanced(XalanC_INCLUDE_DIR) if(XalanC_INCLUDE_DIR AND EXISTS "${XalanC_INCLUDE_DIR}/xalanc/Include/XalanVersion.hpp") _XalanC_GET_VERSION("${XalanC_INCLUDE_DIR}/xalanc/Include/XalanVersion.hpp") endif() if(NOT XalanC_LIBRARY) # Find all XalanC libraries find_library(XalanC_LIBRARY_RELEASE NAMES "Xalan-C" "xalan-c" "Xalan-C_${XalanC_VERSION_MAJOR}" "Xalan-C_${XalanC_VERSION_MAJOR}_${XalanC_VERSION_MINOR}" DOC "Xalan-C++ libraries (release)") find_library(XalanC_LIBRARY_DEBUG NAMES "Xalan-CD" "xalan-cd" "Xalan-C_${XalanC_VERSION_MAJOR}D" "Xalan-C_${XalanC_VERSION_MAJOR}_${XalanC_VERSION_MINOR}D" DOC "Xalan-C++ libraries (debug)") include(${CMAKE_CURRENT_LIST_DIR}/SelectLibraryConfigurations.cmake) select_library_configurations(XalanC) mark_as_advanced(XalanC_LIBRARY_RELEASE XalanC_LIBRARY_DEBUG) endif() unset(XalanC_VERSION_MAJOR) unset(XalanC_VERSION_MINOR) unset(XalanC_VERSION_PATCH) unset(XalanC_XERCESC_REQUIRED) if(XalanC_FIND_REQUIRED) set(XalanC_XERCESC_REQUIRED REQUIRED) endif() find_package(XercesC ${XalanC_XERCESC_REQUIRED}) unset(XalanC_XERCESC_REQUIRED) include(FindPackageHandleStandardArgs) find_package_handle_standard_args(XalanC REQUIRED_VARS XalanC_LIBRARY XalanC_INCLUDE_DIR XalanC_VERSION XercesC_FOUND VERSION_VAR XalanC_VERSION FAIL_MESSAGE "Failed to find XalanC") if(XalanC_FOUND) set(XalanC_INCLUDE_DIRS "${XalanC_INCLUDE_DIR}" ${XercesC_INCLUDE_DIRS}) set(XalanC_LIBRARIES "${XalanC_LIBRARY}" ${XercesC_LIBRARIES}) # For header-only libraries if(NOT TARGET XalanC::XalanC) add_library(XalanC::XalanC UNKNOWN IMPORTED) if(XalanC_INCLUDE_DIRS) set_target_properties(XalanC::XalanC PROPERTIES INTERFACE_INCLUDE_DIRECTORIES "${XalanC_INCLUDE_DIRS}") endif() if(EXISTS "${XalanC_LIBRARY}") set_target_properties(XalanC::XalanC PROPERTIES IMPORTED_LINK_INTERFACE_LANGUAGES "CXX" IMPORTED_LOCATION "${XalanC_LIBRARY}") endif() if(EXISTS "${XalanC_LIBRARY_RELEASE}") set_property(TARGET XalanC::XalanC APPEND PROPERTY IMPORTED_CONFIGURATIONS RELEASE) set_target_properties(XalanC::XalanC PROPERTIES IMPORTED_LINK_INTERFACE_LANGUAGES_RELEASE "CXX" IMPORTED_LOCATION_RELEASE "${XalanC_LIBRARY_RELEASE}") endif() if(EXISTS "${XalanC_LIBRARY_DEBUG}") set_property(TARGET XalanC::XalanC APPEND PROPERTY IMPORTED_CONFIGURATIONS DEBUG) set_target_properties(XalanC::XalanC PROPERTIES IMPORTED_LINK_INTERFACE_LANGUAGES_DEBUG "CXX" IMPORTED_LOCATION_DEBUG "${XalanC_LIBRARY_DEBUG}") endif() set_target_properties(XalanC::XalanC PROPERTIES INTERFACE_LINK_LIBRARIES XercesC::XercesC) endif() endif() cmake_policy(POP)
