[Installation Error for HIBAG.gpu] Cannot find/define the path for opencl.h

[YifangZhang]

Dear HIBAG author,

I have encountered a problem in order to install your HIBAG.gpu version of the package onto a supercomputer (reposted at https://github.com/zhengxwen/HIBAG.gpu/issues/2).

The issue is defining the path for opencl.h file. Based on the documentation, I cannot find any place where I can define the path of opencl.h file. Is there a way to resolve this?

Here is the error log:

Sorry, have not checked HIBAG.gpu for a while. Try setting C_INCLUDE_PATH (for C header files) or CPLUS_INCLUDE_PATH (for C++ header files) environment variables to include $CUDA_HOME/include. You might also need to set an appropriate $LD_LIBRARY_PATH.
