Build: Could NOT find DPL (missing: DPL_INCLUDE_DIR)

[npolina4]

I export DPL_ROOT like in README.md file.

export DPL_ROOT=$(pwd)/oneDPL/include

I try to build and see:

CMake Warning (dev) at CMakeLists.txt:294 (find_package):
  Policy CMP0074 is not set: find_package uses <PackageName>_ROOT variables.
  Run "cmake --help-policy CMP0074" for policy details.  Use the cmake_policy
  command to set the policy and suppress this warning.

  Environment variable DPL_ROOT is set to:

    /localdisk/intel/oneapi/dpl/2021.7.1

  For compatibility, CMake is ignoring the variable.
This warning is for project developers.  Use -Wno-dev to suppress it.

I open FindDPL.cmake and see:

# The following variables are optionally searched for defaults
#  DPLROOT:         Environment variable to specify custom search place

I export DPLROOT and now its work
