build.sh on Ubuntu 14.04 fails with

Please fix build.sh and/or install-build-deps.sh so that it compiles again on Ubuntu 14.04. Thanks.

sudo apt install libgtest-dev does _not_ seem to solve this.

I plan to pull in GTest as a dependency with ExternalProject_Add, too. Ubuntu's GTest distribution has a lot of issues. See https://www.eriksmistad.no/getting-started-with-google-test-on-ubuntu/ on how to initialize it properly, @probonopd, you apparently have to compile(!) something system wide after installing the dev packet because there's no binary package. That's pretty annoying.

[probonopd]

If it's too complicated to get the tests going from build.sh it'd be ok (for me) to disable them when using build.sh and only run them for CMake based builds.

@probonopd as said before, going to change that very soon by using a custom GTest, so, since it works on Travis, I'd ask you to be patient, and wait for a day or two.

[probonopd]

The following is working for me:

sudo apt-get install cmake libgtest-dev
cd /usr/src/gtest
sudo cmake CMakeLists.txt
sudo make

# copy or symlink libgtest.a and libgtest_main.a to your /usr/lib folder
sudo cp *.a /usr/lib

So this would need to be added to build.sh.

[TheAssassin]

It's sudo-ish code, which shouldn't go into build.sh script, but rather install-build-deps.sh. But, as said before, it's really not worth the effort.

This has been resolved since #568 and its subsidiary PRs.
