Can't install from a downloaded ZIP

[cxw42]

Thank you for releasing this project, and under a permissive license! I am trying to install from a downloaded ZIP, and installation fails because it can't get the version number from Git.

To reproduce, on Ubuntu 18.04 x64:

curl -L -o libIntegrate.zip \
  https://github.com/CD3/libIntegrate/archive/bce57026475bb49ce882438bd8f81bdcf2341eaf.zip

unzip libIntegrate.zip
mv libIntegrate-* libIntegrate   # because the dir name has a commit in it
cd libIntegrate
mkdir build
cd build
cmake .. -G Ninja
sudo ninja install

CMake output:

-- The C compiler identification is GNU 7.4.0
-- The CXX compiler identification is GNU 7.4.0

Edit The same is true if I download a tagged ZIP such as https://github.com/CD3/libIntegrate/archive/v0.3.2.zip .

Ah, thank you for bringing this up. I never install from zip, so I haven't run into this. But this should be supported, so I need to rethink how version numbers are detected. Thanks again, I'll look into this.

This should work now. version 0.3.3 includes a version.txt file that will be used if no git repository is found.

Thanks again.

@CD3 Thanks very much for the quick response!
