We had the situation that "make test" runs the test suite but does not
show useful error messages (see
https://github.com/vgough/encfs/issues/358 for an example).
"make check" did the right thing by using the "--output-on-failure"
feature, but depended on "make test" being available as well. This
means users will continue to run "make test".
This commits drops the cmake test logic and adds a dumb "make test"
target that simply runs test.sh.
gcc is default compiler on most distributions, we should
also test with it.
build.sh exists and should be tested as well, so why not use
it in Travis.
test.sh outputs much more details than "make check", so
run it as well.
Additionally, make build.sh and test.sh work when called from
other directories.
On July 18, Travis upgraded their default build VM
to Ubuntu Trusty. Trusty has cmake 3.5.1, which allows us to
drop our bundled version.
We explicitely set "dist: trusty" to prevent our build jobs
from being routed to an older build VM.
* Update cmake
* Update cmake, make Travis use it
* Enable all tests in a single command : make check
* Make cmake flawlessly run with Debian jessie cmake 3.0.2
* Make Travis use our own cmake 3.0.2 compiled version
* Typo in preferred version
* Be sure travis will have gettext
