build on WSL (ubuntu) fails with Python related errors

[AleksandrSokolov]

The make asked to add -DPYTHON=yes by message:

CMake Warning at CMakeLists.txt:176 (message):
Python plugin not enabled by default, use -DPYTHON=yes if you really
want it

After that to build I used:

sudo apt install python3-dev
sudo apt install python3-pip
pip3 install virtualenv
cmake -DUSEWX=yes -DCMAKE_BUILD_TYPE=Release -DPYTHON=yes ..

[AleksandrSokolov]

But still have message:

CMake Warning at CMakeLists.txt:170 (message):
virtualenv not found, python plugin will not be built

[elfmz]

try install it by sudo apt install virtualenv

[elfmz]
