On fresh install of CentOS 7, you will need to install make and libuv-static. But before installing libuv-static you should install epel-release package to enable Epel repo.
So, the instructions should look like this for CentOS:

sudo yum install -y epel-release
sudo yum install -y git make cmake gcc gcc-c++ libuv-static libstdc++-static libmicrohttpd-devel libuv-static
git clone https://github.com/xmrig/xmrig.git
cd xmrig
mkdir build
cd build
cmake .. -DCMAKE_BUILD_TYPE=Release -DUV_LIBRARY=/usr/lib64/libuv.a
make
