Error: INTERNAL_IPP_INC_CORE NOTFOUND

I get the following error when running cmake

-- Intel(R) IPP(static) was found here: C:\Program Files (x86)\Intel\oneAPI\ipp\latest -- folder with libraries: C:/Program Files (x86)/Intel/oneAPI/ipp/latest/lib;C:\Program Files (x86)\Intel\oneAPI\ipp\latest\lib\..\..\..\compiler\lib\intel64 -- folder with includes : INTERNAL_IPP_INC_CORE-NOTFOUND -- Configuring done (0.7s) 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: C:/git/ipp/IPPPlus/bench/INTERNAL_IPP_INC_CORE

cmake 3. 27.2

Windows 11

IPP 2022

I installed IPP in the default directory. I also have 2021.10 installed.The installation resulted in this file structure

C:\Program Files (x86)\Intel\oneAPI\

ipp - 2021.10

- 2022.0

- latest (symlinked to C:\Program Files (x86)\Intel\oneAPI\ipp\2022.0)

- include

- ipp.h

- ipp

- ippcore.h

In FindIPP.cmake, the following sets INTERNAL_IPP_INC_CORE by looking for ippcore.h in the hints paths: PATHS and ${INTERNAL_IPP_INC}

set(INTERNAL_IPP_INC $ENV{IPPROOT}/include) find_path (INTERNAL_IPP_INC_CORE ippcore.h PATHS ${INTERNAL_IPP_INC})

My IPPROOT is set to C:\Program Files (x86)\Intel\oneAPI\ipp\latest

Any thoughts as to why find_path can't find ippcore.h? It is in the "hint" path given to find_path().

After a bit more research (thank-you stack overflow!), it appears find_path() is not recursive.

So it appears the IPPROOT set by setvars.bat won't work (C:\Program Files (x86)\Intel\oneAPI\ipp\latest) because of the include\ipp folder that holds the .h files. The FindIPP.cmake assumes there is no include\ipp folder, just include.

If I add the following to FindIPP.cmake, cmake completes

Another option is to move the 2022.0\include\ipp files to 2022.0\include

There must be something I'm doing wrong though because I can't find others online who have run into this issue.

My bad. I discovered that the FindIPP.cmake I'm using is custom to the repo. I thought it was part of the cmake.

Thank you Eddie for the sharing for your fix

Have you try the followings?

set(INTERNAL_IPP_INC $ENV{IPPROOT}/include)
find_path(INTERNAL_IPP_INC_CORE ippcore.h PATHS ${INTERNAL_IPP_INC}/ipp)

include_directories(${INTERNAL_IPP_INC} ${INTERNAL_IPP_INC_CORE})
