Finding WxWidgets 3.0 from CMake
From Just in Time
My version of CMake (2.8.12.2) didn't find WxWidgets 3.0 after I compiled all libraries/dlls with mingw. Turns out that the included version of FindwxWidgets.cmake searches for library files with specific versions in their filename, and 3.0 is not among them. Specifically, it searches for filenames like
wxbase29${_UCD}${_DBG}.The version below fixes that problem by providing a 30 version wherever a 29 version appears. You should be able to find this file in <cmake-install-dir>\share\cmake-2.8\Modules.
<source lang="text">
- - Find a wxWidgets (a.k.a., wxWindows) installation.
- This module finds if wxWidgets is installed and selects a default
- configuration to use. wxWidgets is a modular library. To specify the
- modules that you will use, you need to name them as components to
- the package:
- find_package(wxWidgets COMPONENTS core base ...)
- There are two search branches: a windows style and a unix style. For
- windows, the following variables are searched for and set to
- defaults in case of multiple choices. Change them if the defaults
- are not desired (i.e., these are the only variables you should
- change to select a configuration):
- wxWidgets_ROOT_DIR - Base wxWidgets directory
- (e.g., C:/wxWidgets-2.6.3).
- wxWidgets_LIB_DIR - Path to wxWidgets libraries
- (e.g., C:/wxWidgets-2.6.3/lib/vc_lib).
- wxWidgets_CONFIGURATION - Configuration to use
- (e.g., msw, mswd, mswu, mswunivud, etc.)
- wxWidgets_EXCLUDE_COMMON_LIBRARIES
- - Set to TRUE to exclude linking of
- commonly required libs (e.g., png tiff
- jpeg zlib regex expat).
- For unix style it uses the wx-config utility. You can select between
- debug/release, unicode/ansi, universal/non-universal, and
- static/shared in the QtDialog or ccmake interfaces by turning ON/OFF
- the following variables:
- wxWidgets_USE_DEBUG
- wxWidgets_USE_UNICODE
- wxWidgets_USE_UNIVERSAL
- wxWidgets_USE_STATIC
- There is also a wxWidgets_CONFIG_OPTIONS variable for all other
- options that need to be passed to the wx-config utility. For
- example, to use the base toolkit found in the /usr/local path, set
- the variable (before calling the FIND_PACKAGE command) as such:
- set(wxWidgets_CONFIG_OPTIONS --toolkit=base --prefix=/usr)
- The following are set after the configuration is done for both
- windows and unix style:
- wxWidgets_FOUND - Set to TRUE if wxWidgets was found.
- wxWidgets_INCLUDE_DIRS - Include directories for WIN32
- i.e., where to find "wx/wx.h" and
- "wx/setup.h"; possibly empty for unices.
- wxWidgets_LIBRARIES - Path to the wxWidgets libraries.
- wxWidgets_LIBRARY_DIRS - compile time link dirs, useful for
- rpath on UNIX. Typically an empty string
- in WIN32 environment.
- wxWidgets_DEFINITIONS - Contains defines required to compile/link
- against WX, e.g. WXUSINGDLL
- wxWidgets_DEFINITIONS_DEBUG- Contains defines required to compile/link
- against WX debug builds, e.g. __WXDEBUG__
- wxWidgets_CXX_FLAGS - Include dirs and compiler flags for
- unices, empty on WIN32. Essentially
- "`wx-config --cxxflags`".
- wxWidgets_USE_FILE - Convenience include file.
- Sample usage:
- # Note that for MinGW users the order of libs is important!
- find_package(wxWidgets COMPONENTS net gl core base)
- if(wxWidgets_FOUND)
- include(${wxWidgets_USE_FILE})
- # and for each of your dependent executable/library targets:
- target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})
- endif()
- If wxWidgets is required (i.e., not an optional part):
- find_package(wxWidgets REQUIRED net gl core base)
- include(${wxWidgets_USE_FILE})
- # and for each of your dependent executable/library targets:
- target_link_libraries(<YourTarget> ${wxWidgets_LIBRARIES})

- NOTES
- This module has been tested on the WIN32 platform with wxWidgets
- 2.6.2, 2.6.3, and 2.5.3. However, it has been designed to
- easily extend support to all possible builds, e.g., static/shared,
- debug/release, unicode, universal, multilib/monolithic, etc..
- If you want to use the module and your build type is not supported
- out-of-the-box, please contact me to exchange information on how
- your system is setup and I'll try to add support for it.

- Miguel A. Figueroa-Villanueva (miguelf at ieee dot org).

- Based on previous works of:
- Jan Woetzel (FindwxWindows.cmake),
- Jorgen Bodde and Jerry Fath (FindwxWin.cmake).
- TODO/ideas
- (1) Option/Setting to use all available wx libs
- In contrast to expert developer who lists the
- minimal set of required libs in wxWidgets_USE_LIBS
- there is the newbie user:
- - who just wants to link against WX with more 'magic'
- - doesn't know the internal structure of WX or how it was built,
- in particular if it is monolithic or not
- - want to link against all available WX libs
- Basically, the intent here is to mimic what wx-config would do by
- default (i.e., `wx-config --libs`).
- Possible solution:
- Add a reserved keyword "std" that initializes to what wx-config
- would default to. If the user has not set the wxWidgets_USE_LIBS,
- default to "std" instead of "base core" as it is now. To implement
- "std" will basically boil down to a FOR_EACH lib-FOUND, but maybe
- checking whether a minimal set was found.
- FIXME: This and all the DBG_MSG calls should be removed after the
- module stabilizes.
- Helper macro to control the debugging output globally. There are
- two versions for controlling how verbose your output should be.
macro(DBG_MSG _MSG)
- message(STATUS
- "${CMAKE_CURRENT_LIST_FILE}(${CMAKE_CURRENT_LIST_LINE}): ${_MSG}")
endmacro() macro(DBG_MSG_V _MSG)
- message(STATUS
- "${CMAKE_CURRENT_LIST_FILE}(${CMAKE_CURRENT_LIST_LINE}): ${_MSG}")
endmacro()
- Clear return values in case the module is loaded more than once.
set(wxWidgets_FOUND FALSE) set(wxWidgets_INCLUDE_DIRS "") set(wxWidgets_LIBRARIES "") set(wxWidgets_LIBRARY_DIRS "") set(wxWidgets_CXX_FLAGS "")
- Using SYSTEM with INCLUDE_DIRECTORIES in conjunction with wxWidgets on
- the Mac produces compiler errors. Set wxWidgets_INCLUDE_DIRS_NO_SYSTEM
- to prevent UsewxWidgets.cmake from using SYSTEM.

- FindPackageStandardArgs.cmake. At the time of this writing
- FindQt4.cmake has a QT4_EXTRACT_OPTIONS, which I basically copied
- here a bit more generalized. So, there are already two find modules
- using this approach.
