How to create a "configure" file?

Recently I downloaded a file using the following link

git clone git://github.com/mapserver/mapcache.git

Inside the downloaded mapcache folder I can not find a configure file to do "./configure". But the installation help file tell:

Unix compilation instructions

If you are using a git clone rather than a tarball distribution, you must first run autoconf in the root directory, to create the configure file from configure.in:

$ autoconf

For unix users, the compilation process should resume to:

$ ./configure

$ make

(as root)

make install-module

The installation script takes care of putting the built module in the apache module directory.

To do ./configure there should be a configure file isn't it? Please show me how to make one to get rid of this problem.

Solution

maintainer speaking ...

mapcache and mapserver are switching to cmake for the next release and the docs for the master branch need updating. You can either use the branch-1-0 branch to continue using autoconf builds, or use cmake with master:

$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
