Cmake 编译另一个库时发生HDF5错误

我按照以下步骤编译了HDF5：

untar hdf5-xxx.tar.gz
cd hdf5-xxx
make
make install

但是，当我安装另一个请求HDF5的库（OpenGM）时，我给出了以下参数：

HDF5_CORE_LIBRARY                /Users/Florian/Documents/THESE/hdf5-1.8.7/hdf5                                                             
 HDF5_CPP_LIBRARY                 /Users/Florian/Documents/THESE/hdf5-1.8.7/c++                                                              
 HDF5_HL_LIBRARY                  /Users/Florian/Documents/THESE/hdf5-1.8.7/hl                                                               
 HDF5_INCLUDE_DIR                 /Users/Florian/Documents/THESE/hdf5-1.8.7/hdf5/include                                                     
 HDF5_Z_LIBRARY                   /usr/lib/libz.dylib

使用CMake和generate后，我得到：

由于这些是“just”警告，我可以编译我的OpenGM库：

make

但我最终犯了以下错误：

<>问题是通过编译HDF5库和——用XCX< /COD>标志建立C++接口。此外，我在

/usr/local

中安装了HDF5库，以便在安装opengm时自动找到它。

。。。其中我提供了HDF5库的路径…

-看起来您将目录分配给了一个变量，该变量应该是库文件。这就是您发出警告的原因。请参阅我的编辑以查看我作为CMake参数给出的内容。正如我之前所说的：您将目录分配给变量（

HDF5\u核心库

，

HDF5\u核心库

），这些变量应该是库文件。按库定义什么？我应该考虑哪些扩展？你可以通过<代码> FordPub包（HDF5）获得变量列表，不是吗？与其手动填充此变量，不如在安装HDF5库的位置提示此过程。

FindHDF5.cmake

脚本中的注释描述了如何提示它。跟着他们，我也有类似的问题。问题是，尽管我可以成功编译OpenGM，但我不能编译一个简单的C++文件，它调用OpenGM库和HDF5。
