fatal error: uWS/uWS.h: No such file or directory

Hi,

Thanks for the useful repository on Path and behavioral planning.

I am getting the below error when I try to build the project using the given steps.

user@computer:~/Github_Repos/behavior-and-path-planning/build$ cmake .. && make
-- Configuring done

make[1]: *** [CMakeFiles/path_planning.dir/all] Error 2

After doing some googling, I found that below solution would fix the error.

cd uWebSockets
# git checkout e94b6e1
mkdir build
cd build
cmake ..
make 
sudo make install

However when I try to implement the above solution, I am getting error as given as I dont see any CMakeLists.txt in the directory.

user@computer:~/Github_Repos/uWebSockets/build$ cmake ..
CMake Error: The source directory "/home/user/Github_Repos/uWebSockets" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.

Could you please help me get this fixed.

Thank you, KK
