MSYS2 CMAKE PATH前缀为Windows格式(C:/），但需要MSYS2/*NIX样式(/C/）才能链接

MSYS2中从PACMAN安装的CMAKE似乎在库和标头/标头/包含c：/的路径上，但是所需的实际路径格式是/c/的前缀。我使用过正则替换为kludge，但这不是一个非常优雅的解决方案，我担心这会破坏Mingw。

仅供参考CMake闭孔的库路径为：

 C:/msys64/mingw64/include/gtk-3.0;C:/msys64/mingw64/include/cairo;C:/msys64/mingw64/include;C:/msys64/mingw64/include/pango-1.0;C:/msys64/mingw64/include/fribidi;C:/msys64/mingw64/include;C:/msys64/mingw64/include/atk-1.0;C:/msys64/mingw64/include/cairo;C:/msys64/mingw64/include/pixman-1;C:/msys64/mingw64/include;C:/msys64/mingw64/include/freetype2;C:/msys64/mingw64/include;C:/msys64/mingw64/include/harfbuzz;C:/msys64/mingw64/include/libpng16;C:/msys64/mingw64/include/gdk-pixbuf-2.0;C:/msys64/mingw64/include/libpng16;C:/msys64/mingw64/include;C:/msys64/mingw64/lib/libffi-3.2.1/include;C:/msys64/mingw64/include/glib-2.0;C:/msys64/mingw64/lib/glib-2.0/include;C:/msys64/mingw64/include

，它需要：

 /c//msys64/mingw64/include/gtk-3.0;/c//msys64/mingw64/include/cairo;/c//msys64/mingw64/include;/c//msys64/mingw64/include/pango-1.0;/c//msys64/mingw64/include/fribidi;/c//msys64/mingw64/include;/c//msys64/mingw64/include/atk-1.0;/c//msys64/mingw64/include/cairo;/c//msys64/mingw64/include/pixman-1;/c//msys64/mingw64/include;/c//msys64/mingw64/include/freetype2;/c//msys64/mingw64/include;/c//msys64/mingw64/include/harfbuzz;/c//msys64/mingw64/include/libpng16;/c//msys64/mingw64/include/gdk-pixbuf-2.0;/c//msys64/mingw64/include/libpng16;/c//msys64/mingw64/include;/c//msys64/mingw64/lib/libffi-3.2.1/include;/c//msys64/mingw64/include/glib-2.0;/c//msys64/mingw64/lib/glib-2.0/include;/c//msys64/mingw64/include

我一直在挖掘解决方案，并看到Windows的Cmake（不是从MSYS2中安装的CMAKE）具有特定于Makysfile发电机，但是必须有一些简单的解决方案来使用MSYS2中可用的CMAKE。我无法想象我是唯一遇到这个问题的人。有人知道干净的解决方案吗？

更新：这是CMakelists.txt，没有正则替换hack。这将失败，错误

C:/msys64/home/username/sample/src/main.cpp:1:10 fatal error: gtk/gtk.h: No such file or directory
 #include <gtk/gtk.h>
compilation terminated.

在制造过程中

    cmake_minimum_required(VERSION 3.12)
    project(sample CXX)
    # Find GTK+ headers/libs with PkgConfig
    find_package(PkgConfig REQUIRED)
    pkg_check_modules(GTK3 REQUIRED gtk+-3.0)
    include_directories(${GTK3_INCLUDE_DIRS})
    link_directories(${GTK3_LIBRARY_DIRS})
    add_definitions(${GTK3_CFLAGS_OTHER})
    set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib/natives)
    set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib/natives)
    set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
    add_executable(sample src/main.cpp)
    target_link_libraries(sample ${GTK3_LIBRARIES})

对于main.cpp，只需使用默认GTK Hello World

    #include <gtk/gtk.h>
    int
    main (int   argc,
    char *argv[])
    {
      GtkWidget *window;
      gtk_init (&argc, &argv);
      window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
      g_signal_connect (window, "destroy", G_CALLBACK (gtk_main_quit), NULL);
      gtk_widget_show (window);
      gtk_main ();
      return 0;
    }

为了使编译起作用，我正在使用以下cmake kludge：

    cmake_minimum_required(VERSION 3.12)
    project(sample CXX)
    # Find GTK+ headers/libs with PkgConfig
    find_package(PkgConfig REQUIRED)
    pkg_check_modules(GTK3 REQUIRED gtk+-3.0)
    # Generated paths starting with "C:" need to be converted to /c/ to work with MSYS2
    # TODO remove this or do it some way better at some point in the future
    if(MSYS OR MINGW)
        string(REGEX REPLACE "C:" "/c/" GTK3_INCLUDE_DIRS "${GTK3_INCLUDE_DIRS}")
    endif(MSYS OR MINGW)
    include_directories(${GTK3_INCLUDE_DIRS})
    link_directories(${GTK3_LIBRARY_DIRS})
    add_definitions(${GTK3_CFLAGS_OTHER})
    set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib/natives)
    set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib/natives)
    set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
    add_executable(sample src/main.cpp)
    target_link_libraries(sample ${GTK3_LIBRARIES})

请注意替换。

要注意的另一件事是我只使用工具，例如cmake和库/标头/等。从PACMAN安装在MSYS2中，我更愿意将其保留，因为我将根据Ruby Native Extension将其推出，而Windows SDK则是基于MSYS2的Windows SDK。同时，我相当确定我的kludge会破坏基于mingw的构建（如果我什至需要担心吗？），这不是很灵活。
