+Before you attempt to build nim-status-client you'll need a few environment variables set:
+
+export QTDIR="/c/Qt/$QtVersion/msvc2017_64"
+export Qt5_DIR="/c/Qt/$QtVersion/msvc2017_64"
+export VCINSTALLDIR="/c/BuildTools/VC"
+
+You might also have to include the following paths in your `$PATH:
+
+export PATH=`"/c/BuildTools/MSBuild/Current/Bin:/c/BuildTools/VC/Tools/MSVC/14.27.29110/bin:`$PATH`"
