Automatically generated CMakeLists.txt ends in error for --cmake autotools

[igormacedo]

I am currently using cget 0.1.7 and cmake 3.5.1 on ubuntu 16.04 lts

I have tried to install libffi v3.2.1 via requirements.txt file, with the following line
libffi,libffi/libffi@v3.2.1 --cmake autotools, but the automatically generated CMakeLists.txt ends execution with the error shown below. Using the command cget install libffi,libffi/libffi@v3.2.1 --cmake autotools results in the same error.

The libffi directly from github does not provide the top-level configure script. It is available if you download it from their ftp site, or from github from the release assets like for 3.3 here.

[pfultz2]

There is a configure.ac file which can be used to generate the configure script. It should probably try to generate it if the configure script is missing.

Thanks! It was really helpful. Problem solved!
