Hello,
We started using CMake recently in our projects. And it is really a timesaver
comparing to Qmake/autotools, however there is one thing that bothers me.
Why typing simple: cmake in command line doesn't trigger configure with default
generator (i.e. Makefile)? It just prints help, which is anyway accessible via
cmake -h/--help.
This is really weird comparing to other tools such as ./configure, quake, make,
that do not expect any parameter to launch them up.
Fortunately there is `cmake .`, but the dot is kinda superfluous.
The preferred way to build with cmake is "out-of-source" [1].
Which means that the source directory remains untouched and all build
artifacts go to a separate build directory.
For that you create an empty directory and call "cmake <path to source
directory>" from it.
This will allow you to have multiple build directories that work with a
single source directory.
It also makes it easier to discard a build.
