Install and Update in CentOS 7

1. Install dependencies:

   yum install cmake cmake-gui
   yum install cairo-devel libcurl-devel
   yum localinstall http://mirror.logol.ru/epel/7/x86_64/e/epel-release-7-2.noarch.rpm
   yum install gdal-devel geos-devel openssl-devel libpqxx-devel proj-devel gtk3-devel wxGTK3-devel libcanberra-gtk3
   

2. Disable wxGIS_HAVE_UNITY_INTEGRATION option in cmake-gui (wxGIS group).

3. Create ld config:

   echo /usr/local/lib > /etc/ld.so.conf.d/ngm.conf
   

Other instructions are the same as for Ubuntu.
