+### Fontconfig_DIR not found in cmake-gui for Ubuntu 18.04
+There is an issue with cmake v3.20+ versions with fontconfig. Just purge all the cmake you have installed before, after that download cmake-3.16.0.tar.gz from https://github.com/Kitware/CMake/releases/tag/v3.16.0
+after that
+```
+./bootstrap
+make -j32
+sudo make install
+```

+You have installed cmake v3.16.0. This version will solve the issue about fontconfig if you have installed correct fontconfig libraries.
