Hi,
I've just tried my FindOpenCL Module in cmake-next, and with 3.0, it
doesn't work as expected (on Windows)
Before I submit the fix, I wanted to check back that I was indeed doing
it wrong before.
In my find_path, I used the following call:
find_path(OpenCL_INCLUDE_DIR
NAMES
CL/cl.h OpenCL/cl.h
PATHS ENV
"PROGRAMFILES(X86)"
AMDAPPSDKROOT
INTELOCLSDKROOT
NVSDKCOMPUTE_ROOT
CUDA_PATH
ATISTREAMSDKROOT
PATH_SUFFIXES
OpenCL/common/inc
"AMD APP/include")
which I had to change to
find_path(OpenCL_INCLUDE_DIR
NAMES
CL/cl.h OpenCL/cl.h
PATHS
ENV "PROGRAMFILES(X86)"
ENV AMDAPPSDKROOT
ENV INTELOCLSDKROOT
ENV NVSDKCOMPUTE_ROOT
ENV CUDA_PATH
ENV ATISTREAMSDKROOT
PATH_SUFFIXES
include
OpenCL/common/inc
"AMD APP/include")
Notice that I have to repeat ENV now for every environment variable, and
I had to add "include" to PATH_SUFFIXES. Without repeating ENV, only the
first environment variable is expanded. However, I cannot find anything
in the CMake 3.0.0 release notes regarding find_path which would explain
why these changes are necessary, and this code used to work with CMake
2.8.12. Is this a regression, or was I simply lucky that it worked?
Cheers,
Matthäus
