我正在尝试用 cmake 编译一些东西，它给出了一个关于需要源代码的错误。请问如何才能找到有关此错误的更多信息？这是输出

C:\Users\sansari\Downloads\tpm_emulator-0.7.4\tpm_emulator-0.7.4\build>cmake ../
CMake Error at CMakeLists.txt:17 (message):
  TPM_Emulator requires an out of source build.

这是 CMakeLists.txt 的内容

@Dan Shepler - 谢谢。我删除了源并再次解压缩。现在我收到一条不同的消息，如下所示：

$ cmake ../
-- The C compiler identification is unknown
CMake Error at CMakeLists.txt:6 (project):
  The CMAKE_C_COMPILER:

    cl

  is not a full path and was not found in the PATH.

  To use the NMake generator with Visual C++, cmake must be run from a shell
  that can use the compiler cl from the command line.  This environment is
  unable to invoke the cl compiler.  To fix this problem, run cmake from the
  Visual Studio Command Prompt (vcvarsall.bat).

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.

Given that I have installed MinGw. I believe I have to set my compiler as gcc. And I believe this would be my path

C:\MinGW\bin

我只是做了这两个命令将环境变量设置为我知道的编译器的路径，但我仍然得到错误。我在 C:\MinGw\bin 中看到了 gcc.exe。我将尝试将 gcc.exe 的名称添加到环境变量路径中。

set CC=C:\MinGW\bin



set CMAKE_C_COMPILER=C:\MinGW\bin

我在构建目录中找到了我需要更改的变量并对其进行了更改。现在它说

$ cmake ../
-- The C compiler identification is GNU 4.9.3
-- Check for working C compiler: C:/MinGW/bin/gcc.exe
CMake Error: Generator: execution of make failed. Make command was: "nmake" "/NOLOGO" "cmTC_5e307\fast"

  The C compiler "C:/MinGW/bin/gcc.exe" is not able to compile a simple test
  program.

  It fails with the following output:

  CMake will not be able to correctly generate this project.

我找到了这个链接并在 Windows 10 上检查了我的路径变量。实际上我必须添加一个用户路径；我只有系统路径。我将 MInGw\bin、msys\bin、msys\local\bin 和 cmake 放在我的路径中。

我认为这次奏效了。我做了什么，我使用了在管理员模式下运行的 cmd，而不是 MinGw shell。这是输出...

此行显式输出消息：

    message(FATAL_ERROR "${PROJECT_NAME} requires an out of source build.")

通常，我不希望根据cmake您给出的命令触发 if 条件。我会首先检查源目录中是否有一些 CMake 工件C:\Users\sansari\Downloads\tpm_emulator-0.7.4\tpm_emulator-0.7.4从之前的配置尝试中遗留下来，这可能导致 CMake 拒绝使用您的构建目录。如果是这样，则从源目录中删除 CMakeCache.txt、CMakeFiles/ 等（或者只是删除整个源目录并再次解压缩）。if(IS_INSOURCE)否则，为了调试正在发生的事情，我会在语句上方临时插入类似这样的内容：

message(STATUS "CMAKE_SOURCE_DIR = ${CMAKE_SOURCE_DIR}")
message(STATUS "CMAKE_BINARY_DIR = ${CMAKE_BINARY_DIR}")
message(STATUS "IS_INSOURCE = ${IS_INSOURCE}")
