The build environment was lacking the possibility to get libcoap
buildable out of tree, simply checkable by the running 'make distcheck'.
Without this fix the users are impossible to build libcoap in a own
folder that's independed from the source containing folder. Typical use
case would be:
$ mkdir libcoap-build && cd libcoap-build
$ /path/to/libcoap-source/configure \
--srcdir=/path/to/libcoap-source \
--prefix=/somethere/to-install
This commit enables the out of tree build by adding and changing some
needed variables.
Doxygen creates various hashfiles (*.md5) to check which files needs to
be re created if the input files has been changed. The user don't need
those hashfiles so let's remove these from final install target.
The old behavior didn't allow a additonal setting of the DESTDIR
variable. This is a serious problem while building within a chroot for
example. Also the implementation of the stamp file was triggering
multiple builds in some cirumstances. This handling is reverted with the
remove of the old stamp file handling.
The make target for creating the distribution tarball (make dist) was
broken some commits ago within the changes in the doc/ subdirectory. The
reason for this is that simple Doxygen has to be runs ones before the
automatism can pick up the files. automake uses dist_pkgdist_DATA as
trigger. So we have to use that variable.
Changing up the makefile template so the call for 'dist_pkgdist_DATA'
*and* 'all-local' is calling 'doxfile.stamp' so fist Doxygen is running.
By doing this also clean up a little bit and prepare the build for be
able to run out of the tree.
To install the doxygen output, which is generated within doc/html/,
adding the needed checks for the doxygen binary to configure.ac and also
adding the needed doc/Makefile.am file.
Finally tuning doc/Doxyfile.in to let the autotools write the needed
informations into this file while generating the finally created
doc/Doxyfile.
