CMAKE找不到OpenNI

Question

我一直在尝试运行Kinect库(http://nicolas.burrus.name/index.php/Research/KinectUseNestk)的“入门教程”，但我偶然发现了一个错误。

当我在CLI中尝试以下行时：

cmake -DCMAKE_BUILD_TYPE=RelWithDebInfo ..

我得到以下错误：

CMake Error at D:/Program Files/CMake 2.8/share/cmake-2.8/Modules/FindPackageHan
dleStandardArgs.cmake:91 (MESSAGE):
Could NOT find OpenNI (missing: OPENNI_LIBRARY OPENNI_INCLUDE_DIR)

Call Stack (most recent call first):

gs.cmake:252 (_FPHSA_FAILURE_MESSAGE)

nestk/cmake/find_nestk_deps.cmake:77 (FIND_PACKAGE)
build/nestk/UseEmbeddedNestk.cmake:23 (INCLUDE)
nestk/CMakeLists.txt:67 (INCLUDE)

有谁知道我要怎么解决这个问题吗？我已经安装了OpenNI，它安装在D:\Program Files\OpenNI。

Answer 1

为了使用CMAKE修改OpenNI项目，你可以在你的cmakelist中写下这段代码。它工作得很好。(我还包含了NITE2，但如果您不需要，只需删除这些行)。

OPTION (ENABLE_OPENNI2_NITE2 ON)

IF( ENABLE_OPENNI2_NITE2 )
set(OPENNI2_DEFINITIONS ${PC_OPENNI_CFLAGS_OTHER})
FIND_LIBRARY( OPENNI2_LIBRARY
             NAMES OpenNI2
             HINTS ${PC_OPENNI2_LIBDIR} ${PC_OPENNI2_LIBRARY_DIRS} /usr/lib
             PATHS "$ENV{PROGRAMFILES}/OpenNI2/Lib${OPENNI2_SUFFIX}" "$ENV{PROGRAMW6432}/OpenNI2/Lib${OPENNI2_SUFFIX}" "$ENV{PROGRAMW6432}/OpenNI2"
             PATH_SUFFIXES lib lib64
)
FIND_PATH( OPENNI2_INCLUDE_DIR OpenNI.h
          HINTS ${PC_OPENNI2_INCLUDEDIR} ${PC_OPENNI2_INCLUDE_DIRS} 
                  /usr/include/openni2 /usr/include/ni2
                  PATHS "$ENV{PROGRAMFILES}/OpenNI2/include" "$ENV{PROGRAMW6432}/OpenNI2/include"
          PATH_SUFFIXES openni2 ni2)

FIND_LIBRARY( NITE2_LIBRARY
             NAMES NiTE2
             HINTS ${PC_OPENNI2_LIBDIR} ${PC_OPENNI2_LIBRARY_DIRS} /usr/lib
             PATHS "$ENV{PROGRAMFILES}/PrimeSense/NiTE2/lib${OPENNI2_SUFFIX}" "$ENV{PROGRAMW6432}/PrimeSense/NiTE2/lib${OPENNI2_SUFFIX}"
             PATH_SUFFIXES lib
)
FIND_PATH( NITE2_INCLUDE_DIR NiTE.h
          HINTS ${PC_OPENNI2_INCLUDEDIR} ${PC_OPENNI2_INCLUDE_DIRS} /usr/include/openni2 /usr/include/nite2
          PATHS "$ENV{PROGRAMFILES}/PrimeSense/NiTE2/include" "$ENV{PROGRAMW6432}/PrimeSense/NiTE2/include"
          PATH_SUFFIXES openni2         
)
ENDIF( ENABLE_OPENNI2_NITE2 )

然后，您需要链接找到的目录和库：

link_directories( ${OPENNI2_LIBRARY} ${NITE2_LIBRARY} )
INCLUDE_DIRECTORIES( ${OPENNI2_INCLUDE_DIR} ${NITE2_INCLUDE_DIR} )
target_link_libraries( project ${OPENNI2_LIBRARY} ${NITE2_LIBRARY} )

Answer 2

您可以尝试修改CMakeLists.txt文件，并添加或修改以下行

set(OPENNI_INCLUDE_DIR "D:/Program Files/OpenNI/Include")
set(OPENNI_LIB_DIR "D:/Program Files/OpenNI/Lib")

否则，在二进制文件文件夹中查找名为CMakeCache.txt的文件。查找OPENNI_INCLUDE_DIR和OPENNI_LIB_DIR，设置正确的路径，然后再次运行cmake。

如果这些都不起作用，并且您可以运行cmake- GUI，请尝试使用cmake-GUI而不是cli命令，并在GUI中手动指定这些路径。

我希望它能有所帮助！

Answer 3

确保OPEN_NI_BIN、OPEN_NI_INCLUDE、OPEN_NI_INSTALL_PATH环境变量都已设置，并且它们指向正确的位置，因为检查OPEN_NI的cmake模块会检查这些值。我得到了同样的错误，但在我的例子中，这是一个混合64位和32位库的问题。我用32位编译器构建opencv，但OpenNI是64位的。所以我卸载了所有的64位版本，只留下了32位版本，这样它就可以工作了。
