Compilation failure on Linux

[izzayacine]

It seems that cmake file is not properly configured.
I am trying to install Marabou on Linux (Red Hat Enterprise Linux release 8.4 (Ootpa)) using the following commands:

cd path/to/marabou/repo/folder
mkdir build 
cd build
cmake ..
cmake --build .

I first get this error:

[  0%] Building CXX object CMakeFiles/MarabouHelper.dir/src/engine/DnCManager.cpp.o
Path/To/Marabou/src/engine/DnCManager.cpp:135:5: error: use of undeclared identifier 'openblas_set_num_threads'
    openblas_set_num_threads( numWorkers );
    ^
Path/To/Marabou/src/engine/DnCManager.cpp:148:5: error: use of undeclared identifier 'openblas_set_num_threads'
    openblas_set_num_threads( 1 );
    ^
2 errors generated.

When I comment these functions in DnCManager.cpp and main.cpp, but I still other errors:

[ 11%] Built target MarabouHelper

And if I use the debug mode, I got error in the tests:

It seems openblas is not correctly installed. Could you share the output when you run

cmake ..
