Issues building dOxygen with cmake - c++

Question

I am trying to compile the source files for dOxygen verseion 1.8.13 using cmake. I have all the correct libraries and compilers properly downloaded and set up, but it still returns errors for me. I downloaded the tar.gz package from the dOxygen website and unpacked them with tar.
I then ran this command to finish compiling (as it says to do on the website):
cmake -G "Visual Studio 15 2017" ..
Which gives me the following printout:
CMake Error at C:/Program Files/CMake/share/cmake-3.8/Modules/FindBISON.cmake:102 (message):
Command "C:/Users/Barr/Documents/bison-2.4.1-bin/bin/bison.exe --version"
failed with output:
Call Stack (most recent call first):

I removed some of the info returned at the beginning of the command since all they did was indicate things that had been done successfully. Is there something I may be missing?

Answer 1

The issue was that I had an out of date version of bison.exe. Updating to a newer version allowed the build to complete succesfully.
