| <p>Find a wxWidgets (a.k.a., wxWindows) installation.</p> |
| <p>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:</p> |
| <p>find_package(wxWidgets COMPONENTS core base ... OPTIONAL_COMPONENTS net ...)</p> |
| <div class="versionadded"> |
| <p><span class="versionmodified added">New in version 3.4: </span>Support for <span class="target" id="index-0-command:find_package"></span><a class="reference internal" href="../command/find_package.html#command:find_package" title="find_package"><code class="xref cmake cmake-command docutils literal notranslate"><span class="pre">find_package()</span></code></a> version argument; <code class="docutils literal notranslate"><span class="pre">webview</span></code> component.</p> |
| </div> |
| <div class="versionadded"> |
| <p><span class="versionmodified added">New in version 3.14: </span><code class="docutils literal notranslate"><span class="pre">OPTIONAL_COMPONENTS</span></code> support.</p> |
| </div> |
| <p>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):</p> |
| <div class="highlight-none notranslate"><div class="highlight"><pre><span></span>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). |
| </pre></div> |
| </div> |
| <p>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:</p> |
| <div class="highlight-none notranslate"><div class="highlight"><pre><span></span>wxWidgets_USE_DEBUG |
| wxWidgets_USE_UNICODE |
| wxWidgets_USE_UNIVERSAL |
| wxWidgets_USE_STATIC |
| </pre></div> |
| </div> |
| <p>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:</p> |
| <div class="highlight-none notranslate"><div class="highlight"><pre><span></span>set(wxWidgets_CONFIG_OPTIONS --toolkit=base --prefix=/usr) |
| </pre></div> |
| </div> |
| <p>The following are set after the configuration is done for both windows |
| and unix style:</p> |
| <div class="highlight-none notranslate"><div class="highlight"><pre><span></span>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. |
| </pre></div> |
| </div> |
| <div class="versionadded"> |
| <p><span class="versionmodified added">New in version 3.11: </span>The following environment variables can be used as hints: <code class="docutils literal notranslate"><span class="pre">WX_CONFIG</span></code>, |
| <code class="docutils literal notranslate"><span class="pre">WXRC_CMD</span></code>.</p> |
| </div> |
| <p>Sample usage:</p> |
| <div class="highlight-none notranslate"><div class="highlight"><pre><span></span># Note that for MinGW users the order of libs is important! |
