Hi, in my daily work, I used the wx libraries installed by the pacman command under msys2 gcc environment. But our wxWidgets project wizard does not support creating a project for those libraries. I have just modify the wizard.script, and here is the patch file:

The patch is very simple, it first add a new variable named "IsMsys2Lib", and by I set it to "true". The wx library supplied by msys2/gcc is using some kinds of Linux format, so I change some code of the wizard.script to follow the condition of the PLATFORM == Unix branch.
To build the generated project, you have to define your global variable named "wx_config".
In my case, it refer to something like below:
wx-config-msys2.exe --prefix=$(TARGET_COMPILER_DIR)
Note that the "wx-config-msys2.exe" can be built from the github repo: https://github.com/eranif/wx-config-msys2 (Thanks eranif)
You can define the "wx_config" to other strings, for example: Re: codeblocks cbp projects for wx samples (https://forums.codeblocks.org/index.php/topic,25105.msg171348.html#msg171348), in this post, if you would like to use a wx library build you self, you can define the string as:
wx-config.exe --prefix=F:/code/wxWidgets-3.2.1 --wxcfg=gcc_dll/mswu
Note the "wx-config.exe" can also be built from the github repo: https://github.com/eranif/wx-config-msys2
Basically, you have to create a user defined wizard.script file under you C::B's APPDATA folder, usually:
%APPDATA%\CodeBlocks\share\codeblocks\templates\wizard\wxwidgets
See this thread New Variable to support wx-config in MSys2 MinGW (https://forums.codeblocks.org/index.php/topic,24974.0.html) to understand how the global variable can be defined and used to support building. (Thanks stahta01)
I have attach the wizard file if you are lazy to apply my patch. :)
If you have any issue, comments are welcome!
This is the v2 of the modified wizard.script.
I add a new option page named wxBuildPlatform where a ChoiceList is used.
Wizard.AddGenericSingleChoiceListPage(_T("wxBuildPlatform"),
_("Please select the wxWidgets build platform want to use"),
_T("Windows;Windows-MSYS2 or Unix"),
IsMsys2Lib); // select wxwidgets build platform
So that the adding of library pages will mainly depends on the user selection. Some of the code are moving from BeginWizard() to OnLeave_WxGuiSelect(), because those pages are added dynamically depends on the previous user choice.
FYI:
I modify the Code::Blocks' opencv project wizard to linking msys2's opencv library(currently, its opencv4)
I put the wizard.script here: https://gist.github.com/asmwarrior/93c3f6f0efa8a826c206446632d856f1
Also, the source code should be updated like below:
#include <opencv2/core/core.hpp>
#include <opencv2/imgproc/imgproc.hpp>
#include <opencv2/highgui/highgui.hpp>
using namespace cv;
int main(int argc, char *argv[])
{
Mat img = imread("arnold_schwarzenegger.jpg", IMREAD_COLOR);
if(img.empty())
return -1;
namedWindow("arnold_schwarzenegger", WINDOW_AUTOSIZE );
imshow("arnold_schwarzenegger", img);
waitKey(0);
return 0;
}
The IMREAD_COLOR and WINDOW_AUTOSIZE is new options for opencv4. Our old wizard using the opencv2 options.
