Can't compile in ubunu 18.10, gcc 8.2, cmake 3.12.1

[emdio]

After following the instructions and launching the make command from the project root I get this error messages:

$ make CMake Warning (dev) at CMakeLists.txt:17 (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.

CMake variable TBB_ROOT is set to:

~soft/git/ELF/third_party/tbb/

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

I was able to compile with GCC 8 and 9 after adding -Wno-cast-function-type -Wno-deprecated-copy to the C and CXX flags in CMakeLists.txt:

set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wno-cast-function-type -Wno-deprecated-copy")

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Werror -Wno-cast-function-type -Wno-deprecated-copy -Wextra -Wno-register -Wno-deprecated-declarations -fPIC -march=native")
