CMake错误: MinGW make要正确工作，sh.exe不能出现在您的路径中
我正试图在MinGW下用Qt5和cmake构建一个"Hello“项目。
这是CMakeLists.txt文件(取自在线文档)：
project(Qt5_cmake_test)
cmake_minimum_required(VERSION 2.8.11)
set(CMAKE_PREFIX_PATH "C:/Qt/Qt5.1.1/5.1.1/mingw48_32")
# Find includes in corresponding build directories
set(CMAKE_INCLUDE_CURRENT_DIR ON)
# Instruct CMake to run moc automatically when needed.
set(CMAKE_AUTOMOC ON)
# Find the QtWidgets library
find_package(Qt5Widgets)
# Add the source files from the current directory
aux_source_directory(. SRC_LIST)
# Tell CMake to create the executable
add_executable(${PROJECT_NAME} WIN32 ${SRC_LIST})
# Use the Widgets module from Qt5
target_link_libraries(${PROJECT_NAME} Qt5::Widgets)源代码是在创建新项目(生成空窗口)时自动生成的代码。
使用：cmake -G "MinGW Makefiles" ..\Qt5_cmake_test从Windows命令提示符进行配置
我知道这些错误：
CMake Error at C:/Program Files (x86)/CMake 2.8/share/cmake-2.8/Modules/CMakeMinGWFindMake.cmake:20 (message):
sh.exe was found in your PATH, here:
C:/Program Files (x86)/Git/bin/sh.exe
For MinGW make to work correctly sh.exe must NOT be in your path.
Run cmake from a shell that does not have sh.exe in your PATH.
If you want to use a UNIX shell, then use MSYS Makefiles.

CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage
CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage
-- Configuring incomplete, errors occurred!因此，它似乎无法找到编译器。有没有办法让cmake自己找到它，或者只给它一个CMAKE_PREFIX_PATH目录？
我必须手动指定makefile中的所有变量还是Windows中的环境变量？
我尝试使用标准Windows命令提示符和Qt提供的命令提示符，结果相同。可以从Windows命令提示符构建，还是应该在MinGW的shell中进行构建？
平台：
Qt 5.1
CMake 2.8.11.2
MinGW/GCC 4.8
Windows 7

此CMakeLists.txt文件正常工作：
project(Qt5_cmake_test)
cmake_minimum_required(VERSION 2.8.11)
set(CMAKE_PREFIX_PATH "C:/Qt/Qt5.1.1/5.1.1/mingw48_32")
# Find includes in corresponding build directories
set(CMAKE_INCLUDE_CURRENT_DIR ON)
# Instruct CMake to run moc automatically when needed.
set(CMAKE_AUTOMOC ON)
# Find the Qt libraries
find_package(Qt5Core REQUIRED)
find_package(Qt5Widgets REQUIRED)
# Add the source files from the current directory
aux_source_directory(. SRC_LIST)
# Tell CMake to create the executable
add_executable(${PROJECT_NAME} WIN32 ${SRC_LIST})
# Use Qt5 modules
target_link_libraries(${PROJECT_NAME}
Qt5::Widgets
Qt5::WinMain)这些变化是：
增加了find_package(Qt5Core REQUIRED)。
将Qt5::WinMain添加到target_link_libraries中。

在运行PATH之前，将git路径从您的cmake中取出。
这样做的神奇之处在于：
set PATH=%PATH:C:/Program Files (x86)/Git/bin;=%Stack Overflow用户

在我对此的一些回答中，我已经描述过了。CMake不喜欢sh.exe。
sh.exe was found in your PATH, here:
C:/Program Files (x86)/Git/bin/sh.exe解决方案:很快重命名C:/Program Files (x86)/Git/bin/sh.exe。
例如：
C:/Program Files (x86)/Git/bin/shxx.exe但别忘了什么都建好了。重命名一次。
