I accidentally discovered a problem with the alarm sounds played by midas.
The javascript code is very simple: var audio=new Audio("alarm.mp3"); audio.play();

|
I want to report a bug in the ROOT build process that might be relevant to the midas implementation. I had an annoying failure to build root 6.18 (current
pro version) with a misleading error message about a fault in the root code. It turned out this was a cmake problem, and the error was from my cmake version
being older than 3.14, which is quite recent. Took a bit of searching to find this.

Each CMakeLists.txt should specify which version of CMake it requires. The MIDAS CMakeLists.txt requires CMake 3.1 or later.
We deliberately stayed away from fancy cutting edge CMake features in order to make midas easier to compile. On top of that,
midas is a much simpler package compared to root, so things are not so complicated.

I just tried CMake 3.1.0 and it worked with midas. So I believe all versions between 3.1.0 and 3.6.1 are ok.
Actually playing around with different versions I realized that 3.0.0 is also ok, so I changed the requirement of midas down to 3.0

I reworked the midas cmake files:
- install via CMAKE_INSTALL_PREFIX should work correctly now:
- installed are bin, lib and include - everything needed to build against the midas library
