MinGW-w64找不到存在的Makefile

Question

我在构建我的一个ExternalProjects时遇到错误：

mingw32-make.exe[3]: *** No targets specified and no makefile found.  Stop.

以下是用于在我的项目中构建它的relevant code：

FIND_PACKAGE(sphinxbase)
if (${SPHINXBASE_FOUND})
    INCLUDE_DIRECTORIES(${SPHINXBASE_INCLUDE_DIR}/sphinxbase/)
else ()
    ExternalProject_Add(
        sphinxbase
        GIT_REPOSITORY      "https://github.com/syb0rg/sphinxbase.git"
        #GIT_SHALLOW         TRUE
        SOURCE_DIR          ${CMAKE_BINARY_DIR}/lib/sphinxbase
        UPDATE_COMMAND      ""
        CONFIGURE_COMMAND   ""
        BUILD_IN_SOURCE     ON
        LOG_DOWNLOAD        ON
        LOG_UPDATE          ON
        LOG_CONFIGURE       ON
        LOG_BUILD           ON
        LOG_TEST            ON
        LOG_INSTALL         ON
    )
    ExternalProject_Get_Property(sphinxbase SOURCE_DIR)
    ExternalProject_Get_Property(sphinxbase BINARY_DIR)
    SET(SPHINXBASE_SOURCE_DIR ${SOURCE_DIR})
    SET(SPHINXBASE_BINARY_DIR ${BINARY_DIR})
    SET(SPHINXBASE_LIBRARIES ${SPHINXBASE_SOURCE_DIR}/bin/Debug/x64/sphinxbase.lib)
    SET(DEPENDENCIES ${DEPENDENCIES} sphinxbase)
    INCLUDE_DIRECTORIES(${SPHINXBASE_SOURCE_DIR}/include/win32)
    INCLUDE_DIRECTORIES(${SPHINXBASE_SOURCE_DIR}/include)
endif ()
SET(LIBS ${LIBS} ${SPHINXBASE_LIBRARIES})

${CMAKE_BINARY_DIR}已正确设置为C:/Users/syb0rg/Dropbox/Development/Khronos/Khronos/build，以下是该文件夹的部分内容：

如您所见，我在指定位置存在Makefile。这里发生了什么？为什么CMake / MinGW找不到它？

停止使用MinGW。

MinGW尚未更新since 2013。它已被Cygwin取代 MSYS2。 MinGW项目甚至没有提供64-bit compiler。

Cygwin可以安装在大约3 minutes，我会试一试。
