# - Find wxWindows installation
# This module finds if wxWindows is installed and determines where the
# include files and libraries are. It also determines what the name of
# the library is. This code sets the following variables:
#
2005-12-15 22:17:43 +03:00
# WXWINDOWS_FOUND = system has WxWindows
# WXWINDOWS_LIBRARIES = path to the wxWindows libraries
# on Unix/Linux with additional
# linker flags from
# "wx-config --libs"
# CMAKE_WXWINDOWS_CXX_FLAGS = Compiler flags for
# wxWindows, essentially
# "`wx-config --cxxflags`"
2005-12-15 22:17:43 +03:00
# WXWINDOWS_INCLUDE_DIR = where to find "wx/wx.h" etc
# WXWINDOWS_LINK_DIRECTORIES = link directories
# WXWINDOWS_DEFINITIONS = extra defines
# deprecated:
# * CMAKE_WX_CAN_COMPILE
# * WXWINDOWS_LIBRARY
# * CMAKE_WX_CXX_FLAGS
# * WXWINDOWS_INCLUDE_PATH
#
2005-12-15 22:17:43 +03:00
# For convenience include Use_wxWindows.cmake in your project's
# CMakeLists.txt using INCLUDE(Use_wxWindows). If you need OpenGL support
# please SET(WXWINDOWS_USE_GL 1) in your CMakeLists.txt *before* you include
# this file.

# -changed variable names to conventions from cmakes readme.txt (Jan Woetzel
# 07/07/2003)
# -added definition WINVER for WIN32 (Jan Woetzel 07/07//2003)
# -added IF(CMAKE_WXWINDOWS_CONFIG_EXECUTABLE) found and changed
# CMAKE_WX_CONFIG to CMAKE_WXWINDOWS_CONFIG_EXECUTABLE (Jan Woetzel
# 07/22/2003)
# -removed OPTION for CMAKE_WXWINDOWS_USE_GL. Force the developer to SET it.
#
# status:
# tested with:
# -cmake 1.6.7, Linux (Suse 7.3), wxWindows 2.4.0, gcc 2.95
# -cmake 1.6.7, Linux (Suse 8.2), wxWindows 2.4.0, gcc 3.3
# -cmake 1.6.7, Linux (Suse 8.2), wxWindows 2.4.1-patch1, gcc 3.3
# -cmake 1.6.7, MS Windows XP home, wxWindows 2.4.1, MS Visual Studio .net 7
# 2002 (static build)
#
# TODO:
# -OPTION for unicode builds
# -change WXWINDOWS_USE_GL to use FindOpenGL.cmake or let the user do it
# -testing of DLL linking under MS WIN32
