找不到wxWidgets (缺少: wxWidgets_FOUND)

Question

我正在使用Ubuntu中的wxWidgets编写一个hello-world级别的程序。

代码编译为

g++ HelloWorld.cpp `wx-config --libs` `wx-config --cxxflags` -o HelloWorldApp -I../inc

maot@HP-Pavilion-dv7:~/Perforce/maot_HP_Pavilion_dv7_full_02/WxWidgets/Learning_01/src$ which wx-config
/home/maot/Perforce/wxWidgets-3.1.0/gtk-build/wx-config
maot@HP-Pavilion-dv7:~/Perforce/maot_HP_Pavilion_dv7_full_02/WxWidgets/Learning_01/src$ 

配置之所以有意义，是因为我将wx- ...which的路径放在了path环境变量中。我自己编译了wxWidgets。

现在我想使用cmake。我的CMakeLists.txt文件尝试：

cmake_minimum_required(VERSION 2.8.9)
project(WxWidgets_Learning_01)

set(CMAKE_CXX_COMPILER /usr/bin/g++)

message("CMAKE_CXX_FLAGS_DEBUG = ${CMAKE_CXX_FLAGS_DEBUG}")
message("CMAKE_CXX_FLAGS_RELEASE = ${CMAKE_CXX_FLAGS_RELEASE}")

set(CMAKE_CXX_FLAGS_DEBUG " -g3 ")
set(CMAKE_CXX_FLAGS_RELEASE "")

message("CMAKE_CXX_FLAGS_DEBUG = ${CMAKE_CXX_FLAGS_DEBUG}")
message("CMAKE_CXX_FLAGS_RELEASE = ${CMAKE_CXX_FLAGS_RELEASE}")

include_directories(../inc)
include_directories(../api/IBJts/source/cppclient/client)
include_directories(../api/IBJts/source/cppclient)

# wxWidgets header files start
include_directories(/home/maot/Perforce/wxWidgets-3.1.0/include)
include_directories(/home/maot/Perforce/wxWidgets-3.1.0/gtk-build/lib/wx/include/gtk2-unicode-3.1)
# wxWidgets header files end

# wxWidgets defines start
add_definitions(-D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -D__WXGTK__)
# wxWidgets defines finish

# Directories with wxWidget libs start
link_directories(/home/maot/Perforce/wxWidgets-3.1.0/gtk-build/lib)
# Directories with wxWidget libs finish

SET(wxWidgets_ROOT_DIR /home/maot/Perforce/wxWidgets-3.1.0/gtk-build/lib)
SET(wxWidgets_CONFIGURATION mswud)

# https://cmake.org/cmake/help/v3.0/module/FindwxWidgets.html
# Note that for MinGW users the order of libs is important!
find_package(wxWidgets COMPONENTS net gl core base REQUIRED)
include(${wxWidgets_USE_FILE})

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wextra -Wall -pthread -lm ")

file(GLOB sources "../src/*.cpp" )
file(GLOB headers "../inc/*.h" )

set(daytrading_sources ${sources} ${headers})

add_executable(WxWidgets_Learning_01 ${sources})
target_link_libraries(${PROJECT_NAME} ${wxWidgets_LIBRARIES})

输出：

我想find_package找不到wxWidgets，我不明白为什么。我不确定这个mswud的事情，因为我找不到关于它的解释；ms听起来像Bill G。我已经尝试了wxWidgets_ROOT_DIR的几个值，但没有成功。欢迎任何帮助: wxWidgets_ROOT_DIR应该有什么价值，mswud有什么好处吗？

我使用-- https://wiki.wxwidgets.org/Compiling_and_getting_started =$(Pwd)选项跟踪前缀。不需要make install，它说。

如何将wx-config的结果放入CMakeLists.txt？

maot@HP-Pavilion-dv7:~$ wx-config --cxxflags
-I/home/maot/Perforce/wxWidgets-3.1.0/gtk-build/lib/wx/include/gtk2-unicode-3.1 -I/home/maot/Perforce/wxWidgets-3.1.0/include -D_FILE_OFFSET_BITS=64 -DWXUSINGDLL -D__WXGTK__ -pthread
maot@HP-Pavilion-dv7:~$ 
maot@HP-Pavilion-dv7:~$ wx-config --libs

我使用下面的CMakeLists.txt文件编译和运行我的代码；我意识到这不是事情的本意。

如果你只需要为原型编译一个简单的例子，那么这就是它。

然而，如果你需要编译一些大的项目-你可以尝试设置Anjuta/CodeBlocks/CodeLite来帮助你。从长远来看，这将使您受益(特别是CodeBlocks)。

关于你的问题: mswud并不好，因为它(顾名思义)适用于Windows。

此外，对于include/lib目录，您应该使用wx-config适当的命令，就像您用于命令行编译一样。

您还可以尝试在trac.wxwidgets.org中查看TobiasT所做的CMake工作。
