我在构建我的一个外部项目时遇到错误:

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

这是 relevant code用于在我的项目中构建它:

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} 正确设置为 C:/Users/syb0rg/Dropbox/Development/Khronos/Khronos/build，这里是文件夹的哪一部分看起来像:

如您所见，我在指定位置有一个 Makefile。这里发生了什么？为什么CMake/MinGW找不到？

最佳答案

停止使用 MinGW。

MinGW 尚未更新since 2013 .它已被 Cygwin 取代，并且 MSYS2。 MinGW 项目甚至不提供 64-bit compiler .

Cygwin可以安装在大约3 minutes ，我会试一试。

关于windows - MinGW-w64 找不到存在的 Makefile，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/41642635/
