（tortoisesvn）SVN项目上的CMAKE ::配置过程出错，项目文件可能无效

Question

I have checked out a version of project from SVN. Below are the different kinds of errors I got while trying to CMAKE a project from SVN. Could it be that some of the files are not checked out ? Please, go through the three kinds of errors and help me out with it.

==================Type 1==================================
CMake Error at CMakeLists.txt:184 (add_subdirectory): add_subdirectory given source "google/gmock" which is not an existing directory.

==================Type 2==================================

Subversion executable was not found. CMake Error at CMakeLists.txt:14 (UpLinqSVN_WC_INFO): Unknown CMake command "UpLinqSVN_WC_INFO". Call Stack (most recent call first): CMakeLists.txt:207 (CreateVersionInfo)

========================TYPE 3==========================================

CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: FFMPEG_AVCODEC_LIB linked by target "UpLinq" in directory C:/Users/Krishna/Desktop/2.5/GUI FFMPEG_AVCORE_LIB linked by target "UpLinq" in directory C:/Users/Krishna/Desktop/2.5/GUI FFMPEG_AVDEVICE_LIB linked by target "UpLinq" in directory C:/Users/Krishna/Desktop/2.5/GUI

Configuring incomplete, errors occurred!

Answer 1

Error 1 indeed indicates that the CMakeLists.txt expected there to be a directory called google/gmock (relative to the CMakeLists.txt which is calling add_subdirectory at line 184).

Without more info, there's no way to tell if this is an error in the CMakeLists file or in the repository.

The first part of error 2 (can't find Subversion exe) looks like a custom error message. It may be looking for a ".svn" folder in the project root, and assuming that Subversion is available. Presumably it then looks for the Subversion exe and fails to find it (not in path maybe?)

The second part of error2 (unknown CMake command) is saying that at line 14 of CMakeLists.txt, there's a command called UpLinqSVN_WC_INFO being invoked. It doesn't recognise this as a valid command, which probably means that it's defined as a function or macro in another CMake file somewhere. It would need to be defined before it's invoked at line 14. It could be that the CMakeLists.txt you're executing is expected to be run as part of a larger build, which would define this function before starting on your CMakeLists.txt.

Error 3 is saying that there's a CMake target called "UpLinq" (an exe or lib) which has a dependency on ${FFMPEG_AVCODEC_LIB} . At some point, there's probably been a find_library call looking for the avcodec library which has also failed. The result of the search is held in the variable FFMPEG_AVCODEC , and it shows that ${FFMPEG_AVCODEC} has a value of FFMPEG_AVCODEC-NOTFOUND .

If you need more help than this, you'll need to put up a copy of the relevant parts of the CMakeLists files involved, and a bit more info about your environment / directory structures.
