Building using cmake Fails

[murthy95]

I have followed the instructions to compile and build the project to obtain .so files.
But unfortunately I couldn't succeed linking the shared library libOpenFaceWrapper.so

I have already installed OpenFace and it is verified as well. Now I continued this step by downloading the project and running
make -D OPENFACE_DIR='Open-Face-Path' -D CMAKE_CXX_COMPILER=g++-8 -D CMAKE_C_COMPILER=gcc-8 -D CMAKE_BUILD_TYPE=RELEASE .. -D COMPILE_FLAGS=-fPIC

But in the next step cmake --build . --target OpenFaceWrapper -j 4

I am not sure whats the reason. Can someone help me fix this ?
